C 180 ft2
D 90 fre?

Answer 1

315 ft²

Explanation:

•Split the shape into a triangle and a square.

•A=bh so 15*15=225 (area of square)

•Since the height of the square is 15, subtract given height of 3 from 15 which is 12 and that is the base of triangle.

• To find the height, subtract 15 since the base is equal to the top side.

•A=1/2bh for triangles so 1/2(15)(12) is 90.

•Add 225 and 90 then boom. 315ft²
