FINDING AREA, PERIMETER, AND CIRCUMFERENCE - Idaho State University

1. The perimeter of a parallelogram is the sum of its four sides. Since a parallelogram has two equal short sides (width, w) and two equal long sides (length, l), perimeter = 2l + 2w P = 2l + 2w w 4 P = (2*5) + (2 * 4) P = 10 +8 l 5 P = 18 2. The area of a parallelogram is equal to its base (another name for length) times its height.
