C. 29 ft

D. 84 ft

Answer 1

The answer is 84. Since a triangle is half of a square you have to 1st fine the formula for the area of a base, which is: base x height. So then since a triangle is half of that you do... 21 x 8 = 168 then 168/2 = 84. So in conclusion 84 is ur answer (last choice, D) @lilcece
