Question

The perimeter of a square can be represented by the expression 8x - 10 + 8x - 10. Write an expression to represent the length of one side of the square. Show your work.

Answer 1

The length of one side of the square is
`(4x-5) units`

Explanation:

we know that

The perimeter of a square is equal to

`P=4b`

where

b is the length of one side of the square

In this problem we have

`P=8x-10+8x-10`

`P=16x-20`

substitute

`16x-20=4b`

solve for b

`b=(16x-20)/4`

`b=(4x-5) units`
