The length and width of the rectangle together is 15 cm. What is the length and width of the rectangle

The length and width of the rectangle together is 15 cm. What is the length and width of the rectangle if the width is twice as short?

1. Let’s say that the width of the given rectangle is x cm.

2. Since the length of this rectangle is 2 times greater than its width, therefore, it is 2 * x cm.

3. Let’s make an equation and calculate what the width of this rectangle is if we know that the sum of the length and width of the rectangle is 15 cm.

x + 2 * x = 15;

3 * x = 15;

x = 15/3;

x = 5 cm.

4. Now let’s calculate what the length of the rectangle is.

5 * 2 = 10 cm.

Answer: The width of the rectangle is 5 cm, the length is 10 cm.
