What the surface area of the regular square pyramid? is (figure is not drawn to scale.)7 cm9 cm a) 120.5 cmo b) 144 cm c) 207 cm
d) 333 cm

The answer is C. 207 cm. The formula to find the area of a triangle is 1/2 base times height. So the base is 9cm and the height is 7cm. Multiply them and you get 63, but you have to divide by 2 because the formula so you get 31.5 cm. Multiply that by 4 because there are four triangles. So you get 126 cm. Then to find the area of the square, you do s times s. Side times side so 9 times 9 is 81. Add the 81 and 126 together and your answer is 207. hope i helped ya!!

The third question is correct.
