Question

Craig has 72 feet of material to build a fence around a rectangular flower bed on his property. If the width of the fence must be 3 feet, what is the length of the fence in yards if he uses all 72 feet of material

Answer 1

33 feet.

Explanation:

Perimeter of a rectangle = 2*width + 2*length.

So here we have:

2*3 + 2*L = 72 where L = the length.

2L = 72 - 6 = 66

L = 33 feet.
