The width of a rectangle is 7 inches less than its length. The area of the rectangle is 120 square inches. Solve for the dimensions of the rectangle.
Suppose the width of the rectangle is w, then the length is w + 7. The area is w(w + 7) = 120, solve the equation we get w = 8 inches, so length is 8 + 7 = 15 inches.
