Finding the Area of a Trapezoid

Area of Trapezoids

​MAP Testing Lesson 3

The formula for the area of a trapezoid is 1/2 the

sum of the two bases times the height.

Let's try it!

The bases of this trapezoid are 6 units and 10 units. The height of this trapezoid is 7 units.

A = 1/2 (6 + 10)(7)

A = 1/2 (16)(7)

A = (8)(7)

A =56

So, the area of the trapezoid is 56 square units.
