For a rectangle, the ratio of length to width is 14:5. If the length is reduced by 13 cm, the width is increased by 13 cm, and the area is increased by 18 square cm, the area of the original rectangle can be calculated

For a rectangle, the ratio of length to width is 14:5. If the length is reduced by 13 cm, the width is increased by 13 cm, and the area is increased by 18 square cm, the area of the original rectangle can be calculated

The area of a rectangle is equal to length * width. Although the length is reduced by 13, the width is increased by 13, so the area you mentioned is increased by 18, which is impossible! Therefore, your problem does not exist·
