Question

Paul's dad is putting up a fence in part of the backyard. the length of the fence will be 20 ft and the width will be 15 ft what is the perimeter of the fence?A.68 ftB.35C.70

Answer 1

The length of the fence is l = 20 ft.

The width of the fence is w = 15 ft.

The formula for the perimeter of fence,

`P=2(l+w)`

Determine the perimeter of fence.

`\begin{gathered} P=2(20+15) \\ =2\cdot35 \\ =70 \end{gathered}`

Thus perimeter of fence is 70 ft.
