Jordan was putting wallpaper around her room. The room has four walls that are all the same size. If one wall in her bedroom measures 14 feet by 6 feet, how much wallpaper will she use for her entire room? Explain your thinking.

336 square feet.

Step-by-step explanation:

There are 4 walls in Jordan's bedroom that have the same size and each wall measures 14 feet by 6 feet.

She was putting wallpaper around her room and she wants to know how much wallpaper she needs.

To find how much wallpaper she will need, we need to find the area of each wall and multiply it by 4.

The area of each rectangular wall is:

A = L * B

where L = length and B = breadth

Therefore:

A = 14 * 6 = 84 square feet.

This is the area of each wall. The area of the 4 walls is therefore:

84 * 4 = 336 square feet

The amount of wallpaper she needs is 336 square feet.
