Area of Trapezoids

Area of TrapezoidsObjective: To find areas of trapezoids.

Area of TrapezoidsAt the end of this lesson you should be able to answer the following question.

How is the area for finding the area of a trapezoid related to the formula to find the area of a parallelogram?

Area of TrapezoidsA trapezoid is a four sided polygon that has one pair of opposite sides parallel. The sides that are parallel are called “bases”.

base 1

base 2

Area of TrapezoidsA parallelogram is two congruent trapezoids.

base 1 base 2

base 2 base 1

Area of TrapezoidsThe area of a trapezoid can be found by the following formula:

A = b₁

b₂
