Jorge plans to paint a bedroom wall that is shaped like a trapezoid.
The bottom edge of the wall is 22.5 feet long, and the top edge of the wall is 9.5 feet long.
If the wall is 8 feet tall, what is the area of the wall?

Sagot :

A=1/2 bh
A= 22.5*9.5= 213.75 / 2
A =106.875 

 i hope this is what you wanted because in my school the form of the question is different

*Copy and pasted NOT my answer*

Length of the bottom edge of the wall (a) = 22.5 feet

Length of the top edge of the wall (b) = 9.5 feet

Height of the wall (h) = 8 feet

Then

Area of the wall = [(a + b)/2] * h

                         = [ (22.5 + 9.5)/2] * 8 square feet

                          = (32/2) * 8 square feet

                          = 16 * 8 square feet

                          = 128 square feet

As can be seen from the above deduction, the area of the wall is 128 square feet. I hope the procedure is not complicated for you to understand. You can normally use this method in future for solving similar type of problems without requiring any additional help.

(128 ft squared is the answer)
