You find the area of a trapezoid by using the formula h(b1+b2)/2, where "h" is equal to the height of the trapezoid and b1 and b2 are the lengths of each of the bases, in no particular order. In this case, h=8, b1=29.4 or 4.8, and b2=29.4 or 4.8. As a result, you can now just substitute all of these known values into this formula.
