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

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

1. Suppose that the first side of the rectangle is x cm long.

2. Since the second side has a length of 2 cm longer, therefore it will be equal to (x + 2) cm.

3. Let’s make an equation and find out what the first side of the rectangle is equal to, if it is known that the sum of the length of these two sides is 12 cm.

x + (x + 2) = 12;

x + x + 2 = 12;

2x = 12 -2;

2x = 10;

x = 10/2;

x = 5 cm.

4. Let’s calculate what is the second side of the given rectangle.

5 + 2 = 7 cm.

Answer: The length of one side of the rectangle is 5 cm, the length of the second side is 7 cm.
