What is the area of this trapezoid? Enter your answer in the box. units2 A rectangle with a length of 3 and a height of 8 has two right triangles on each side of it with short leg lengths of 7.

80 units²

Step-by-step explanation:

The area (A) of a trapezoid is

A = h (a + b)

where h is the height and a, b the parallel bases.

Here a = 7 + 3 + 7 = 17 , b = 3 and h = 8, thus

A = × 8 × (17 + 3) = 4 × 20 = 80 units²
