The length of the rectangle is 24 cm, and the width is 8 times less. Find the area and perimeter of this rectangle.

We will solve this task in steps and explain each of them in detail.
1) 24: 8 = 3 centimeters – the width of the rectangle, since it is 8 times less than the length of the rectangle, and the length of the rectangle is 24 centimeters;
2) 2 * (24 + 3) = 2 * 27 = 54 centimeters – the perimeter of a rectangle with a length of 24 centimeters and a width of 3 centimeters;
3) 24 * 3 = 72 square centimeters – the area of a rectangle with a length of 24 centimeters and a width of 3 centimeters.
Answer: 54 centimeters; 72 centimeters square.
