cm, Base 2 =22 cm, Height =7 cm. (Show all of your work)

Answer 1

129.5 cm²

Explanation:

The area (A) of a trapezoid is calculated as

A =
`(1)/(2)` h(a + b)

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

Here h = 7, a = 15 and b = 22 , thus

A =
`(1)/(2)` × 7 × (15 + 22)

= 0.5 × 7 × 37

= 129.5
