Question

If a perfect square has a side length of x+2 and a perimeter of 44cm what is the value of x?

Answer 1

The value of x is 9.

Explanation:

Given that:

Side length of square = x+2

Perimeter of square = 44 cm

As all sides of a square are equal, therefore,

Perimeter of square = 4s

Putting all the values,

44 = 4(x+2)

44 = 4x+8

44-8 = 4x

36 = 4x

4x = 36

Dividing both sides by 4

`(4x)/(4)=(36)/(4)\\x=9`

Hence,

The value of x is 9.
