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
