# One side of the rectangle is 8 cm larger than the other. Find the sides of the rectangle if its perimeter is 28 cm.

Let one side of the rectangle be equal to x cm, then the second side is equal to (x + 8) cm. The perimeter of the rectangle is known, it is equal to 28 cm.
The perimeter of a rectangle is calculated as the sum of the length and width times two. P = 2 * (a + b). Let’s make the equation:
2 * (x + x + 8) = 28,
(x + x + 8) = 14,
2x + 8 = 14,
2x = 14-8,
2x = 6,
x = 3.
One side of the rectangle is 3 centimeters long. Let’s calculate the value of the second side of the rectangle:
1) 3 cm + 8 cm = 11 cm length of the second side.
Answer: the lengths of the sides of the rectangle are 3 centimeters and 11 centimeters.
