So to find the area of a Triangle you want to use the equation:

A=B*H/2.

So for the base we use 18 and for the Height we use 8.

Then just do the equation. A=18*8/2=72in.

So to find the area of a Trapezoid you want to use the equation:

A=1/2h(b₁+b₂)

So the numbers we will be using is: 7,7,15.

Put the numbers in the equation: A=1/2(7)(7+15).

Then just do the equation. A=1/2(7)(7+15)=77yards
