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

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

We will solve this problem using an equation with one unknown.

1) One side of the rectangle is x centimeters.

2) The other side of the rectangle is (x + 2) centimeters.

3) Let’s compose and solve the equation.

x + x + 2 = 12;

2x = 12 – 2 = 10;

2x = 10;

x = 10/2 = 5;

x = 5;

Answer: One side of the rectangle is x = 5 centimeters. The other side of the rectangle is x + 2 = 5 + 2 = 7 centimeters.
