Answer:

625 unit²

Explanation:

Surface area of a rectangular pyramid :

Area of base * 4(area of triangular side)

Area of base = length * width

Area of base = 15 * 15 = 225

Height of triangular side = 15

Area of triangle = 1/2 * base * height

Area of triangle = 1/2 *15 * 15 = 112.5 unit²

Surface area = 225 + 4(112.5)

Surface Area = 225 + 450

Surface Area = 625 unit²
