Answer:

Step-by-step explanation:

Square A:

Area = 225 square feet

side *side = 225

        Side =√225

                 [tex]=\sqrt{15*15}[/tex]

   Side of square A = 15 ft

Square B:

Area = 400 square feet

Side =√400

       = [tex]\sqrt{20*20}[/tex]

Side of square B = 20 ft

Use Pythagorean theorem for finding the side of Square C.

Side of square A is the altitude ;  side of square B is the base and side of square C will be the hypotenuse

hypotenuse² = base² + altitude²

                      = 15² + 20²

                       = 225 + 400

                       = 625

hypotenuse = [tex]\sqrt{625} =\sqrt{25*25}[/tex] = 25 ft

Area of square C = 625 square ft

In short,

Area of square C = area of square B + area of square A

                             = 400 + 225

                             = 625 square ft
