Answer:
105 square inches
Explanation:
area of a triangle = 1/2( base * height)
The base is 5 and the height is 8.
= 1/2 ( 5 *8)
= 1/2(40)
= 20
The area of each triangle = 20 sq inches
So 4 triangles x 20 sq inches each = 80 sq inches.
The area of the square is 5 x 5 = 25 sq inches.
Add them together.
80 + 25 = 105 square inches
