Question 262785
Let's call the length L and the width W.  Then since the length is five times the width, we have that L = 5W.  Now, remembering that the perimeter of a rectangle is 2L+2W, we have

2L+2W=108

Now using the fact that L=5W we have:

2(5W)+2W=108
10W+2W=108
12W=108
W=9

So the width is 9m, which makes the length 9*5=45m.
