We first need to know how much fencing would be needed. We can get this from the perimiter of the playground, knowing that it is a rectangle:
\(P=2(l+w)=2(66+42)=2(108)=216'\)
then we need to convert to yards to compare to the avialble fencing:
\(216' \times \frac{1yd}{3ft} = 72yards\)
and since 72yd<75yd, yes there is enough fencing.
