Its the same as a square! you do base x height and for explaination just say if u split the parallelagram in half and put it together it makes a square!
Imagine he second side is x so the first side is (x-3) and the third side is (x+4)
So x + (x-3) + (x+4) = 34

3x=33
X=11
So longest side is (x+4) so 11+4=15
