The rectangular playground is surrounded by a fence. The length of this platform is 15 m longer than its width

The rectangular playground is surrounded by a fence. The length of this platform is 15 m longer than its width. The sum of the two long sides is 80m. Find the length of the entire fence.

First, you need to determine the value of the length of one long side.

Divide 80 meters by the number of sides.

80/2 = 40 meters.

Since we know that the width of the playground is 15 meters less than the long side, its value will be:

40 – 15 = 25 meters.

To find the length of the entire fence, you need to determine the perimeter of the playground.

To do this, multiply the sum of its length and width by 2.

2 * (25 + 40) = 2 * 65 = 130 meters.

Answer: The length of the fence of the site is 130 m.
