The width of the rectangular section is 38 m and the length is 18 m longer. A fence was built around

The width of the rectangular section is 38 m and the length is 18 m longer. A fence was built around the perimeter of this section, find the length of the fence.

In this problem, the length of the fence = perimeter (P) and is calculated using the formula for the perimeter of the rectangle: P = 2 * a + 2 * b, where a is the length of the rectangle, b is the width of the rectangle, and P is the perimeter of the rectangle.

Find the length (a) of the rectangle, for this you need to add 18 and 38 (In our case):

a = 18 + 38 = 56;

Find the perimeter (P) using the above formula:

P = (2 * 38) + (2 * 56) = 76 + 112 = 188 meters.

Based on the condition, the perimeter (P) is equal to the length of the fence.

Answer: The length of the fence is 188 meters.
