Instructions

    • 1

      Determine the units of measure you will be using, such as feet. The perimeter of a square is the distance around the outside of the square. The perimeter is measured in linear units.

    • 2

      Measure the length of one side of the room. Since a square has four equal sides, the perimeter can be found by multiplying the length of one side by four.

    • 3

      Solve the formula by multiplying. For example, if one side of the square room is 7 feet long, multiply 7 times 4 for a perimeter of 28 feet.
