Question

A fence around a square garden is made up of 4 equal sized pieces that are each 5 1/2 feet long. Matt decided to make the sides 2 1/2 times longer. How much fencing does he need in all?

Answer 1

Find the perimeter of the original square: P = 4s = 4 * 5.5 ft = 22 ft
Now multiply by 2.5 * 22 ft * 22 = 55 ft
He needs 55 ft of fencing
