A trapezoid has bases of lengths 13 cm and 17 cm. The
height of the trapezoid is 9 cm. What is the area of the
trapezoid?

135 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = h(a + b)

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

Here h = 9, a = 13 and b = 17 , thus

A = × 9 × (13 + 17)

   = 0.5 × 9 × 30

   = 135 cm²
