Question

A rectangle has a perimeter of 64. the width is 3 less than the length. the equation for the scenario is 2x 2(x â€"" 3) = 64. what does the variable x represent in the equation? what will finding x â€"" 3 determine?

Answer 1

The  variable x represent the length of rectangle.

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Perimeter= 64 units

let the length be x.

So, width = x - 3

So, Perimeter of rectangle = 2 ( l + w)

64 = 2( x+ x -3)

32 = 2x -3

29= 2x

x= 29/2

Hence, the variable x represent the length of rectangle.
