The variable x represent the length of rectangle.
<h3>What is Algebra?</h3>
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.
