What is the area, in square kilometers, of a trapezoid with bases 5 km and 7 km and height 3 km?




A.

14.5


B.

18


C.

36


D.

52.5

Answer 1

The area of a trapezoid is 1/2*h*(b1 + b2) where h is the height, b1 and b2 are the two base lengths.

A = 1/2*h*(b1 + b2)

A = 1/2* 3 * (5 + 7)

A = 1/2 * 3 * 12

A = ? @jkgjmgk
