Find the side length of the park. A = s² 21) You are considering buying a square wall poster that has an area of 6.25 square feet. Find the side length of the wall poster. The formula for the perimeter of a square is P = 4s, where s is the length of a side. Find the perimeter of each square. 22) Area = 144 square inches 25) What is √ 23) Area = 49 square feet 24) Area = 324 square meters ? Think…what times itself gives you –25?
