Given a square poster's total area, the length of its side can be calculated by finding the** square root **of the area. If the area is 6.25 square feet, its square root (and therefore the length of each side of the square) is 2.5 feet. ;
The side length of a square wall poster with an area of 6.25 ft² is 2.5 feet. We find this by taking the square root of the area. Therefore, each side of the poster measures 2.5 feet.
