Excerpt
Perimeter and area are two different terms that help us know how big or small an object is. The perimeter of an object is the sum of the length of all of the sides. For example, the perimeter of a square would be the sum of the four sides of the square.

If a square is four feet on each side, we can add up the four sides to determine the perimeter of the square:

4 ft + 4 ft + 4 ft + 4 ft = 16 ft

In other words, the perimeter of the square is 16 feet. To find the perimeter of an object, we would use the following equation:
p = l + w

In other words, the perimeter of an object equals the length of its sides plus the width of its sides.
