One side of the rectangle is 8 cm and the adjacent one is 7 cm larger. What is the perimeter of the rectangle?

We will solve this task in steps and explain each of them in detail.
1) 8 + 7 = 15 centimeters – the length of the adjacent side of the rectangle, since it is 7 centimeters longer than the side, which is 8 centimeters;
2) 2 * (8 + 15) = 2 * 23 = 43 centimeters – the perimeter of a rectangle with sides of 8 centimeters and 15 centimeters.
Answer: 43 centimeters.
