Question

A rectangle is 8 cm longer than it is wide the perimeter of the rectangle is 72 cm how wide is the rectangle

Answer 1

18cm

Explanation:

wide = 8cm + length

perimeter = 2(L + B)

Answer 2

32cm

Explanation:

Let x represent the width

if the width = x

therefore the length = x+8

The perimeter = 72cm

Now write it as an equation

`x + x + 8 = 72`

`x + x + 8 - 8 = 72 - 8`

`x + x = 64`

`x + x = 2x`

`2x = 64`

`(2x)/(2) = (64)/(2)`

`x = 32`
