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?

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

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
