The area of a rectangle is 72 cm. The width is twice its length. What is the length and width of the rectangle? The perimeter i. Since rectangle has two lengths and two breadths hence the equation is,. Contact Us. Grades 6 7 8 9 10 11 Toggle navigation. Algebra in Everyday Life. Going shopping. You purchased 10 items from a shopping plaza, and now you need plastic bags to carry them home.
If each bag can hold only 3 items, how many plastic bags you will need to accommodate 10 items? Explanation :. In this article, we will grasp instances in real life where applications of algebra are needed and examples of applications of algebra in real life.
Algebra is a part of mathematics that deals with symbols and the standards for controlling those symbols. The more basic parts of algebra are called elementary algebra, and the more abstract types are called Abstract Algebra or modern algebra.
Let us consider the pattern below. It has been created using marbles. Here we see that the first column has 2 marbles, the second column has 3 marbles, the third column has 4 marbles and so on. Thus we observe that every new column increases by 1 marble.
We can write the representation as. Here n represents the position of the column. A variable is a number that does not have a fixed value. The picture and the list below show some real-life examples, where the value of a variable changes with the change in place and time. The value remains fixed for specific numbers that represent quantities or ideas that will not change. For example, the date of birth of a particular person, the normal human body temperature and capacity of a given container.
Now we will see how to frame an algebraic expression. The rules are that variables are to be represented with alphabetic letters, say lower case a-z and constants in numeric form. Amanda has 10 storybooks more than Alex. Express the number of storybooks Amanda has in terms of the number of storybooks Alex has. Sweets from a big box are equally distributed in 10 small boxes. Express the number of sweets in one small box in terms of the total number of sweets.
Let us see how practical applications of algebra can be used to solve equations. This is an equation in the variable x. This is the trial and error method where we substitute different values for the variable that satisfies the given equation. An equation has two parts which are connected by an equal to sign. Four circles balance one square and a circle on the other side.
The idea is we have to find out how many circles will balance a square. If we remove the circle from the left pan, we have only the square there. Since we removed a circle from the left pan, we have to remove the circle from the right pan also. Then there will be three circles in the right pan. Now the balance looks like the one shown on the right. This is called the principle of balances.
Using balancing equations, we can solve equations in a systematic way. After the determination of the area of the pool, you will calculate the amount of water to fill in the pool and also the time which will be taken to fill the pool to its brim or half the volume; which again requires algebra.
While making plans is a part of organizational leadership. Building a house involves measurements which is vaguely math not algebra. My Aunt is a District manager with LAUSD and passed both algebra 2 and trigonometry but forgot both due to the lack of applicable scenarios over the years despite her promotions. Can anyone give give me some other reasons for using algebra in real life because its an assignment in my math class.
Its a big joke…. Basic mathematics covers it. How many boards do I need for the porch deck? Simple math. Prev Article Next Article. Early Life In the early stages of development, an infant makes use of algebra to calculate trajectories and you might be surprised to know how! Professional Advancement In whatever field you want to strive ahead, algebra is going to be needed.
Morning Routine Right from the time a person wakes up in the morning, algebra comes into play. Sports Algebra does not even leave behind sports to make use of it.
Cooking You might think that algebra has no role to play in the kitchen, especially while cooking. Technology Had it not been for algebra, you might not be having flat screen TVs or smartphones. Logical Thinking The study of algebra helps in logical thinking and enables a person to break down a problem first and then find its solution. Home Improvement Repairing and remodelling of homes require the knowledge of numbers.
Outdoor Landscaping Landscaping is yet another area which requires a person to not only be good with numbers but also basic algebraic operations. Pool Suppose you just brought a new home and you want a pool in your backyard. Image Sources pngtree. Related Posts. Cornel Martin. No thanks, I will just buy me a tailor made equation for my next swimming pool project. They visualize the shapes and patterns and solve puzzles only because of certain Algebraic equations that they may come to know about in later stages of their education.
So, though without cognition, kids gather spatial intelligence by applying Algebra. On growing up as an adult, people work to earn.
They may require to find their tax liability. The process involves doing calculations like finding the tax rebate cap and proportioning the earnings to find how the income is to be divided into various investment options. This process of finding tax liability is based on doing algebraic calculations where the variables are income, the qualifying amount for the rebate, etc.
Algebra helps the workers to structure their income and expenses and get the taxable salary figure in hand. Astrologers predict various events on the basis of planetary movements.
All these calculations are nothing but Algebra whose concept of linear or quadratic equation balancing comes into play when these predictions are made. The Father of Algebra mentioned in the first half of this section did make use of Algebra to contribute to various findings related to astronomy and astrology in his time.
Any innovations around us could not be possible without Algebra. If you decode the functioning of an LED TV and dig into its internal atmosphere, you will find that these TVs are making use of planes, angles, and axes as variables and apply algebraic concepts in the development of various types of screens.
The variations in monitor sizes without the problem of distortion of the picture are achieved with the help of Algebra knowledge that allows designers to fiddle with a variety of dimensional options. We all are budget planners in some or the other capacity.
And, apparently, we make use of Algebra in structuring the budget so that all expenses, intended investment aims, and the overall cash in hand can be fixed and altered.
The changing conditions like inflation, an increase in the number of family members, etc. This is when you may appreciate the learning of Algebra, and its use in daily life. It is the most common activity that anybody does. And, it does involve Algebra quite deeply. Though you may not realize that you have used it, the fact still holds true.
