Perimeter of parallelogram = 2×(sum of two adjacent sides)
Let the adjacent sides be 
and b.
So, A/Q
 2×(a+b)=36
(a+b)=18..............[
36 canceled out by 2]

it is given that all opposite and adjacent sides are equal.
So, 
2a=18..........(adjacent sides are equal)
a=9

We know that the area of ||gm= a
×h
Here representing altitude.
So, 9
×h=90
h=90/9
h=10 cm

Altitude of ||gm is 10 cm.
