Question

The area of a rectangular doghouse floor is 15 square feet. The length of the floor is five feet. What is the perimeter of the floor of the doghouse?

Answer 1

Since area is length x width and the length is 5, then that means that the width is 3 feet. And since perimeter is length pus width plus length plus width:
5+5+3+3
The perimeter is 16 feet.

Answer 2

The perimeter is 16 feet
