The width of the rectangle is 2 times less than the length. Find the area of a rectangle if its perimeter is 120 meters.

We will solve this problem using the equation.

1. Let’s denote by x the width of the rectangle.

2. Find the length of the rectangle.

x m * 2 = 2x m.

3. Calculate the perimeter of the rectangle.

(x + 2x) * 2 = 3x * 2 = 6x m.

4. Let’s compose and solve the equation.

6x = 120;

x = 120: 6;

x = 20.

5. The width of the rectangle is x = 20 m.

6. Determine the length of the rectangle.

20 m * 2 = 40 m.

7. Let’s calculate the area of the rectangle.

20 m * 40 m = 800 m2.

Answer: The area of the rectangle is 800 square meters.
