Let's denote the width of the rectangle by W.

From the problem, we know that the length of the rectangle is 4 meters less than 2 times the width, or:

L = 2W - 4

We also know that the perimeter of a rectangle is given by:

P = 2L + 2W

Substituting the expression for L into the perimeter equation, we get:

P = 2(2W - 4) + 2W
P = 4W - 8 + 2W
P = 6W - 8

We are given that the perimeter is 34 meters, so we can set P equal to 34 and solve for W:

34 = 6W - 8

42 = 6W

W = 7

Therefore, the width of the rectangle is 7 meters.

Answer:

7

Let's call the width = x

width : x

so (x + 2x-4)2 = 34 (perime formula of a rectangle) x+2x-4 = 7

3x = 21

x = 7

so x is 7
