square centimeters. Enter the answer as decimal number
14 cm
8 cm
7 cm
8 cm
21 cm
The solution is

Answer 1

122.5

Explanation:

Use the area formula for a trapezoid (attached below as an image):

A = area in sq cm

a = top base

b = bottom base

h = height

Correspond the correct values with the variables:

a = 14

b = 21

h = 7

A = 1/2 * (14 + 21) * 7

A = 1/2*(35)*7

A = 17.5 * 7

A = 122.5 sq cm
