Suppose that the width of a rectangle is 3 centimeters less than two-thirds of its length. The perimeter of the rectangle is 114 centimeters. Find the length and width of the rectangle.

Step 1. Let x be the length and let 2x%2F3-3 be the width

Step 2. Perimeter P means adding up all four sides of a rectangle.

Step 3. Then,

x%2Bx%2B%282x%2F3-3%29%2B%282x%2F3-3%29=114
