Question

A rectangular garden is designed to be 8 ft longer than it is wide. Let x represent the width of the garden. Write an expression for the perimeter in terms of the width x. Write the expression in simplest form.

Answer 1

perimeter = 4x+16

Explanation:

Let x = width, then length = x + 8

`\boxed{perimeter = 2(length + width)}`

`perimeter=2(x + x+8)`

`=2(2x+8)`

`=4x + 16`
