Answer:
336 square feet.
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.
