Question

Steve is adding wallpaper to a living room wall and he needs to know how much wallpaper to buy. If the wall is 8.5 feet tall and 12.5 wide, how much wallpaper should he buy?

Answer 1

He needs to buy 106.25 square feet of wallpaper. This is area so you would do length times height. 8.5x12.5

Answer 2

Answer:

1.1 × 10² ft² of wallpaper

Step-by-step explanation:

Given data

• Height of the wall (h): 8.5 feet

• Width of the wall (w): 12.5 feet

The wall is a square, so we can calculate its area (A) using the following expression.

A = h × w

A = 8.5 ft × 12.5 ft

A = 1.1 × 10² ft²

Steve should buy 1.1 × 10² ft² of wallpaper.
