The width of a rectangle is three seventh of its length. If the length is reduced by 23 cm and the width is increased by 13 cm, it will become a square. What is the area of the original rectangle? Use the formula
Length of rectangle = (23 + 13) / (1-3 / 7) = 63
Width of rectangle = 63 * (3 / 7) = 27
Area = 63 * 27 = 1701 square centimeter
