Perimeter=60cm
Hypotenuse = 25cm
So (Perpendicular+Base) =60-25= 35cm
We can assume using Pythagoras theorem that the values of the Perpendicular and the base are, 20cm and 15cm respectively or vice-verse.
Now area of a right angled triangle is,
1/2*b*h
1/2*20*15=150 sq. c.m.
Therefore, area is 150 sq. c.m.

I’m confident with this answer. Hope it helps. :)
