The rectangle is 8 cm longer than wide and 2.3 cm wide. Find the perimeter and area of the rectangle.

We will solve this task in steps and explain each of them in detail.
1) 2.3 + 8 = 10.3 centimeters – the length of the rectangle, since it is 8 centimeters larger than its width, and the width is 2.3 centimeters;
2) 2 * (10.3 + 2.3) = 2 * 12.6 = 25.2 centimeters – the perimeter of a rectangle with a length of 10.3 centimeters and a width of 2.3 centimeters;
3) 10.3 * 2.3 = 23.69 square centimeters – the area of a rectangle with a length of 10.3 centimeters and a width of 2.3 centimeters.
Answer: 25.2 centimeters; 23.69 square centimeters.
