Acomposite figure is formed by combining a square and a triangle its total area is 32.5 ft2 the area of the triangle is 7.5 ft2 what is the length of each side of the square

Area of square = Composite Area - Area of Triangle

                          =    32.5  - 7.5  = 25

Area of square = 25 square feet.

Formula for area of square = s²

s²  = 25

s = √25

s = 5

Length of each side of square = 5 feet.
