Answer 2

Calculation of Rectangle Sides

To find the sides of the rectangle, we can set up the following equation based on the given information:

Let's assume the width of the rectangle is x meters. Since the length is 10 meters greater than the width, the length would be x + 10 meters.

The perimeter of a rectangle is given by the formula: Perimeter = 2 * (Length + Width).

Given that the perimeter of the rectangle is 140 meters, we can set up the equation as follows:

140 = 2 * (x + (x + 10))

Now, let's solve this equation to find the value of x.

2 * (x + (x + 10)) = 140

Simplifying the equation:

2 * (2x + 10) = 140

4x + 20 = 140

4x = 120

x = 30

Therefore, the width of the rectangle is 30 meters and the length is 30 + 10 = 40 meters.

So, the sides of the rectangle are 30 meters and 40 meters.
