The perimeter of the rectangle is 28 cm, one of its sides is 2 cm larger than the other. Find the area of the rectangle.

Let’s take one side of the rectangle as x, then x + 2 is the second side. The perimeter of a rectangle is equal to the sum of all its sides. Let’s compose and solve the equation:
x + x + (x + 2) + (x + 2) = 28;
4 * x + 4 = 28;
4 * x = 24;
x = 6 (cm) – one side of the rectangle.
x + 2 = 6 + 2 = 8 (cm) – the second side of the rectangle.
The area of a rectangle is equal to the product of its sides:
6 * 8 = 48 (cm ^ 2) – the area of this rectangle.
Answer: 48 cm ^ 2 is the area of a rectangle.
