Question

The area of a square backyard is 79 ft?. The owner is looking to get fencing to enclose the yard, so they need to find the approximate length of each side of the backyard AND what is the perimeter of the backyard?

Answer 1

According to the given question we have the following:

The area of a square backyard is 79 ft

Therefore if the area of a square backyard is 79 ft that means that length of each side would be the following:

length of each side=area of a square backyard/2

length of each side=79 ft/2

length of each side=39.5

Therefore if 39.5 is lenght of each side, the perimeter of the backyard would be calculated as follows:

perimeter of the backyard=l+l+l+l

perimeter of the backyard=39.5+39.5+39.5+39.5

perimeter of the backyard=158
