One side of the rectangle is 2 cm longer than the other.

One side of the rectangle is 2 cm longer than the other. The total length of these two sides is 12 cm. Find the length of each side of this rectangle.

We will solve the problem using an equation with one unknown, that is, one of the quantities that needs to be found will be denoted by x (x).

1). The length of one side of the rectangle is x centimeters.

2). The other side is equal to (x + 2) centimeters.

3). Let’s compose and solve the equation.

x + (x + 2) = 12;

x + x + 2 = 12;

2x = 12 – 2 = 10;

x = 10/2 = 5;

Answer: One side of the rectangle is x = 5 centimeters.

The other side is x + 2 = 5 + 2 = 7 centimeters.
