Draw a diagram and convince yourself that the perimeter P=2(L+W)

We're told that W=(3/4)L.

We're also told that P=50 when W+2 and L+2 are used. So

50=2((L+2) + (W+2))=2((L+2) + ((3/4)L + 2))

simplifying

25=(L + (3/4)L + 4)

21=(7/4)L

Solve for L then use the relation between W and L given above, i.e. the first sentence of the problem.
