An isosceles right-angled triangle has area 32 $$cm^2$$​. The length of its hypotenuse is in cm

Correct option is C

An isosceles right-angled triangle has two equal sides and one right angle (90∘). Let the equal sides be a cm. The area of the triangle is given by:
​$$1/2. a^2 = 32$$​​
​$$a^2 = 64$$​​
a = √64 = 8 cm)
Now, using the Pythagoras theorem:
$$Hypotenuse ^2$$​ = $$a^2 + a^2$$​​
$$Hypotenuse ^2$$​ = 64 + 64 = 128
Hypotenuse = √128
