Question

A rectangle has a length of x + 2, a width of 7, and a perimeter of 32, what is the value of x?

Answer 1

The perimeter of a rectangle is given by `P = 2L xx 2W`, where P is perimeter, L Is length and W is width.

`32= 2(x + 2) + 2(7)`

`32 = 2x+ 4 + 14`

`32 - 18 = 2x`

`14 = 2x`

`x = 7`

Hopefully this helps!
