Hi
Isosceles right angled triangle MEANS perpendiculat and base are equal.
Now area of triangle is 1/2(base)(height)= 200
(base)(height)= 400 but base and geight are equal that means..
base^2 = 400
base= 20
So height = 20
by pythagoras theorem : Hypoteneous = 20root(2)

Now find the perimeter by adding all the sides.
