Use the formula p = 2(l + w) to find the perimeter of a rectangle, where p is the perimeter, l is the length, and w is the width of the rectangle. The length of a rectangle is one inch less than three times the width. The perimeter of the rectangle is 62 inches. What equation can you use to find the width of this rectangle?

• 62 = 2w + 2(3w – 1)

• 62 = 2w + 2(1 – 3w)

• 62 = 2(3w) + 2(w – 1)

• 62 = w + (3w – 1)
