Question

a. in other to build a fence, does charlene need to find the area or the perimeter of the garden? 
b. How much fencing materials does she need ?

Answer 1

well do you need to find the area or perimeter

Answer 2

The perimeter because the fence goes AROUND the yard, not in it.

P = 2w + 2l

P = 2(60) + 2(20)

P = 120 + 40

P = 160

Charlene needs 160 meters of fencing material.
