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

1. Let the smaller side of the rectangle be x, then the larger side is 2 + x. Let’s compose the expression for the perimeter, solve the resulting equation:
2 * x + 2 * (2 + x) = 28,
2x + 4 + 2x = 28,
4x + 4 = 28,
4x = 28 – 4,
4x = 24,
x = 24/4,
x = 6.
2.find the larger side of the rectangle:
6 + 2 = 8 cm.
3. Find the product of the larger and smaller sides, we get the area of the rectangle:
Area = 6 * 8 = 48 cm2.
