The length of the rectangle is 2 times its width. Find the sides of the rectangle if it is 50 cm longer than its width.

Let’s take the width of the rectangle as X, then its length is 2X, since it is 2 times the width. It is known that the length is 50 cm more than the width, we will compose and solve the equation:

2X – X = 50;

X = 50 (cm) – the width of the rectangle.

2 * X = 2 * 50 = 100 (cm) – the length of the rectangle.

Let’s check the solution of the equation:

2 * 50 – 50 = 50;

50 = 50.

Answer: 50 cm width of the rectangle, 100 cm length of the rectangle.
