Luis, Rebecca, Jordan, and Christina each measured the size of their rectangular rooms. They each wrote down the width and length of their rooms on the board. The width of the 4 rooms are: 12 feet, 7 feet, 6 feet, and 10 feet. The length of the 4 rooms are: 20 feet, 16 feet, 17 feet, and 7 feet.

Can you figure out the width and length of each person's room?

1. The length of Luis' room is seven feet longer than the width.


2. Jordan's room is in the shape of a square.


3. If the length of Rebecca's room is increased by nine feet, the perimeter will be increased by eighteen feet.


4. Christina's room has a perimeter of sixty-four feet.
