Question

The face of a lamp shade is shaped like a trapezoid. The dimensions of the face are shown in the diagram.

Which equation can be used to find A, the area of the face of the lamp shade in square inches?


A = 1/2(6 + 10)yA = 12(6 + 10)y

A = 1/2(6) + (10)xA = 12(6) + (10)x

A = 1/2(6 + 10)xA = 12(6 + 10)x

A = 1/2(6) + (10)yA = 12(6) + (10)y

Answer 1

A = (1/2)* (6+10) * x

Explanation:

A = (1/2)* (6+10) * x
