Let's let the width be represented by x.

According to the problem, the length is four meters less than twice the width. So, we can say that the length is 2x - 4.

The formula for the perimeter of a rectangle is P = 2L + 2W. Plugging in the given values, we get:

100 = 2(2x - 4) + 2x

Simplifying, we have:

100 = 4x - 8 + 2x

100 = 6x - 8

Adding 8 to both sides, we have:

108 = 6x

Dividing both sides by 6, we get:

x = 18

Therefore, the width of the rectangle is 18 meters.
