Question

3.

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?

Answer 1

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

Explanation:

Area = 1/2(b₁ + b₂)h

Area =

1/2 x 16 x height

8 x (x)

8x.

Answer 2

Option B
`A = (1)/(2)(6 +10) x` can be used to find the area of the face of the lamp shade in square inches

Explanation:

We know that the area of the Trapezoid is

Area
`A = (a + b)/(2) h`

where

a and b are the parallel sides

h is the height

Substituting the values from the figure

`A = (6 + 10)/(2) x`

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