The first square is 40 square feet because 8 x 5 = <<8*5=40>>40

The second square is 70 feet because 10 x 7= <<10*7=70>>70

The third square is 25 feet because 5 x 5 = <<5*5=25>>25

The total square footage is 135 feet because 40 + 70 + 25 = <<40+70+25=135>>135

The flag will be 9 feet tall because 135 / 15 = <<135/15=9>>9
