The rectangular playground has a length of 18 m, its width is 4 m shorter

The rectangular playground has a length of 18 m, its width is 4 m shorter than the length. What is the length of the fence around this playground?

To solve this problem, remember that the perimeter of a rectangle is the sum of the lengths of all its sides. Since in a rectangle the opposite sides are equal, then P = 2 * (a + b), where a is the length, b is the width. Let’s calculate what the width of the rectangle is.

18 – 4 = 14 cm.

Let’s calculate what the perimeter of the rectangle is.

2 * (14 + 18) = 32 * 2 = 64 centimeters.

Answer: 64 centimeters.
