Geometry Math 8th (Area of a Trapezoid)

Question

The windshield in a truck is in the shape of a trapezoid. The lengths of the bases of the trapezoid are 70 inches and 79 inches. The height is 35 inches. Find the area of the glass in the windshield.

Answer 1

The formula for the area of a trapezoid is $\dfrac {a+b}2\times h$, so that becomes $\dfrac {149}2\times35 = 2,607.5$inches$^2$

Answer 2

The average of the two bases is 74.5, and I multiply that by the height which is 35 to get 2607.5 inches.
