Answer: A) 200 square inches

Explanation:

First, use Pythagorean Theorem to find the base of each triangle.

a2 + b2 =c2

20 with a 2 on top + b2=(28 1/4 on top) 2 on top

b2= 398.0625

b= 19.9515037

Finally, use the area of a triangle formula to find the area of each triangle.

A= 1/2bh

A=1/2 (19.9515037) (20)

A= 199.515037

Therefore, the area of each triangle is approximately 200 in².
