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:
1.1 × 10² ft² of wallpaper
Step-by-step explanation:
Given data
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.
