\text{Length}=18.5\ m

Explanation:


Let's say, width of the pool is w. Then the length according to the requirement would be, w+13.

We have given the perimeter so, write down the formula for the perimeter and put the given values as:

P=2(l+w)

48=2(w+13+w)

Solve for w to get:

4w+26=48

w={48-26}/4

w=5.5

l=13+5.5=18.5


That's it!

The length of the swimming pool is 18.5m.

Explanation:

Let x be the width of the swimming pool.
2(x+x+13) = 48
2x+13 = 24
2x = 24 - 13
2x = 11
x = 11/2
x = 5.5

The length is 13m more than the width, so it is 18.5m.
