Using the formula A=l•w solve the following word problem. You have enough wallpaper to cover 240 square feet. If your walls are 8 feet high, what wall length can you paper?

a. Wall length of 40 feet

b. Wall length of 30 feet

c. Wall length of 3 feet

d. Wall length of 16 feet

Hi there! The answer is B.

You have enough wallpaper to cover 240 square feet. If your walls are 8 feet high, what wall length can you paper?

First write down our dа ta:

A = 240 square feet

l = 8 feet

Now we can fill in the formula

240 = 8 * w

Switch sides.

8 * w = 240

Divide both sides by 8.

w = 240 / 8 = 30

Therefore the answer is B.

Wall length of 30 feet
