FIGURE 1 Solve the formula P ෇ 2L ϩ 2W for W. This formula gives the relationship between the perimeter (distance around) a rectangle, P, the length of the rectangle, L, and the width of the rectangle, W. See Figure 1. Solve the formula for W by getting W alone on one side of the equals sign. To begin, subtract 2L from both sides. P ෇ 2L ϩ 2W Step 1 Subtract 2L. P Ϫ 2L ෇ 2L ϩ 2W Ϫ 2L P Ϫ 2L ෇ 2W Step 2 is not needed here. P Ϫ 2L 2W Step 3 ෇ Divide both sides by 2. 2 2 P Ϫ 2L P Ϫ 2L ෇ W or W ෇ 2 2 Now Try Exercise 9.
