Answer:
A= b1+b2 dvided by 2 times the height.
Step-by-step explanation:
Recall that the bases are the two parallel sides of the trapezoid. The altitude (or height) of a trapezoid is the perpendicular distance between the two bases. This is equivalent to the altitude times the average length of the bases.
