The length and width of the rectangle together is 6cm. What is the length and width

The length and width of the rectangle together is 6cm. What is the length and width of the rectangle if the length is 2 times greater than its width.

Let us introduce the notation:
Suppose that the width of the rectangle is x cm.By the condition of the problem, the length of the rectangle is 2 times the width, so the length will be 2 * x = 2x cm.
Let’s compose and solve the equation:
Together, the length and width of the rectangle are 6 cm, so:
2x + x = 6;
3x = 6;
x = 6: 3;
x = 2.
Hence, the width of the rectangle is 2 cm.
Determine the length of the rectangle:
2 * x = 2 * 2 = 4 (cm).
Answer: The length of the rectangle is 4 cm and the width of the rectangle is 2 cm.
