The total fencing around a square field is 80 yards. the field has an area of how many square yards?

area of a sqaure is the length of one side squared. so you need to calculate the length of a side.

 since they say the area around the square is 80 divide that by the number of sides (4) so 80/4 = 20.

 so a side is 20 yds. A=20^2 = 400 square yards
