Jesse needs a carpet of size 10 square feet to cover her room. If her room is 10 feet long What is the width of her room?
1. We know that the area of a square is length * width, so we can set up the equation: 

10 = length * width 

2. We also know that the room is 10 feet long, so we can plug that in for length: 

10 = 10 * width 

3. Now we can solve for width: 

10 = 10 * width 
10/10 = (10 * width)/10 
1 = width 

So, the width of the room is 1 foot.
