Ella and Jake love to skateboard. They created a frame for the ramp and then covered it with wood. How much wood did it take to cover the ramp, including the bottom?
Give an exact answer (do not round).

triangle side = 0.54

so both triangle sides = 1.08

and then the sides (1.5 * 3.5) * 2 = 10.5

the last side = 0.9 * 3.5 = 3.15

so add it all  3.15 + 10.5 +  1.08

total area = 14.73 m^2

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
