Question

Sam wants to wallpaper the back wall of his bedroom. The wall is in the shape of a rectangle. Its length is 12 feet and its width is 11 feet. Suppose wallpaper costs $9 for each square foot. How much will wallpaper cost for the wall?

Answer 1

Hey!

Your answer is $1,188!

Explanation:

To find the total area of the wall in square feet, we need to multiply the width and height... 12ft x 11ft = 132 square feet *it's square because its area*

If the price per square foot for the wallpaper is $9 we can calculate the total amount by doing...

132 (sq/ft) x ($)9 (the area x the price)

Which gives us the total of $1,188!

Answer 2

Alright, let's solve this step by step.

First, we need to calculate the total area of the wall. For a rectangle, we can find this by multiplying the length and the width of the rectangle. So, for Sam's bedroom wall, which has a length of 12 feet and a width of 11 feet, the area would be 12 feet * 11 feet = 132 square feet.

Now we need to calculate the cost of the wallpaper. We are given that the wallpaper costs $9 per square foot. So, to find the total cost of the wallpaper, we take the cost per square foot and multiply it by the total area of the wall.

Therefore the total cost of the wallpaper would be $9 per square foot * 132 square feet = $1188.

So, the wallpaper for Sam's wall will cost him $1188.
