66 dm is the perimeter of the rectangle.
3/11 of the perimeter is the length of the side of the rectangle.
66: 3/11 = (66: 11) * 3 = 6 * 3 = 18.
18 cm side length of the rectangle.
(66 – (18 * 2)) / 2 = (66 – 36) / 2 = 30/2 = 15.
15 cm width of the rectangle.
18 * 15 = 270.
270 cm2 area of a rectangle.
Solution: 270 cm2 is the area of a rectangle.
