Answer:
4 units long.
Step-by-step explanation:
The 2 legs of an isosceles right angles triangle are equal .
So the area = 1/2 * x^2 where x = length of a leg.
1/2x^2 = 4
x^2 = 8
x = √8
So the length of the hypotenuse is found using the Pythagoras theorem:-
h^2 = (√8)^2 + (√8)^2
h^2 = 16
h = 4 (answer).
