The perimeter of the rectangle is 0.36 m. Its length is 2 times its width. What is the area of the rectangle?

1. Determine the width of the rectangle. Let the width of the rectangle be a meters, then the length of the rectangle will be 2a meters. Let’s make the equation:

(a + 2a) x 2 = 0.36;

3a x 2 = 0.36;

6a = 0.36;

a = 0.36: 6;

a = 0.06 m;

2. Determine the length of the rectangle:

0.06 x 2 = 0.12 m;

3. Determine the area of the rectangle:

0.06 x 0.12 = 0.0072 m².

Answer: 0.0072 m² is the area of a rectangle.
