Question

Perform the following area application.

You are going to convert a bedroom in your home to an office. You wish to cover the four walls with panel board (standard size 4' × 8') halfway up each wall. Each wall measures 8 feet in height and 12 feet in length.
Assuming no loss, how many panels will you need?

_______ panels.
A) 3
B) 5
C) 6
D) 1

Answer 1

8 x 12 = 96 sq ft 
4 x 8 = 32 sqft 

96 / 32 = 3 panels 

3 x 4 = 12 panels. I'm not sure which answer that would be. :-( If any, I would select C.) 6 panels. 

Answer 2

Answer:

C

Step-by-step explanation:

You will cover halfway up each wall. Since the total height of the wall is 8 feet, you will cover half of that, which is 4 feet.

Length is 12 feet and full length will be covered.

So area covered in 1 wall is $4*12=48$ sq. ft.

There are 4 walls, so total area to be covered is $4*48=192$ sq. ft.

Each panel board is 4 feet by 8 feet, so 1 panel board's area is $4*8=32$ sq. ft.

So number of panel boards required to cover 192 sq. ft. with 32 sq. ft. boards is $\frac{192}{32}=6$

So we need 6 panels. Answer choice C is right.
