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?

Option B    can be used to find the area of the face of the lamp shade in square inches

Step-by-step explanation:

We know that the area of the Trapezoid is

Area

where

a and b are the parallel sides

h is the height

Substituting the values from the figure

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

Step-by-step explanation:

Area = 1/2(b₁ + b₂)h

Area =

1/2 x 16 x height

8 x (x)

8x.
