Answer 4

What is the area of the triangle? There are 2 of them. Calculate the area of one and then the other.

Answer 5

12 square feet?

Answer 6

or you can just calculate the area of that single big triangle

A = (b*h)/2

A = (14.1*9)/2

A = 63.45

Answer 7

now divide that result by 12 to get 63.45/12 = 5.2875 and round up to get 6

Answer 8

thts a big number

Answer 9
