One side of the rectangle is twice as large as the other, the total length of the two sides is 12 cm

One side of the rectangle is twice as large as the other, the total length of the two sides is 12 cm, find the length of each side.

Let one side of the rectangle be x cm.Then, according to the problem statement, it is said that the other side is 2 times larger, so the second side of the rectangle is 2x cm.The total length of the two sides is (x + 2x) cm, which, according to the condition of the problem, was 12 cm. and solve the equation:

x + 2x = 12;

3x = 12;

x = 4 (cm) – one side of the rectangle. Then the second side of the rectangle is 2x = 2 * 4 = 8 cm.

Answer: One side of the rectangle is 4 cm and the other side of the rectangle is 8 cm.
