Answer:
108 cm cubed
Step-by-step explanation:
(1/2 of length•height)•width
(1/2 of 6•4)•9
(1/2 of 24) •9
12•9
108
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!!
