the length and which one is called the width. In math terms, this means times the length plus two times the width. = 2 × 2 P l + × w 4 cm 6 cm = 2 × 2 P l + × w P = 2 x 6 + 2 x 4 P = 12 + 8 P = 20 cm The perimeter of EVERY figure is always calculated in the units given in the question. If the units in the figure are cm, the perimeter is cm; if it is in inches, the perimeter is in inches, and so on. When solving word problems, ALWAYS draw a diagram to help you! ASSIGNMENT 5 PERIMETER – Calculate the perimeter of the following figures. Show your work and include the proper units in your answer. 1a) 18.3 cm 8.5 cm b)
