the ration of sides of a right angled triangle is 1:1: square root2

if the lenght of hypotenuse is 8 root 2 then sides should be 8 but then perimeter will be 8+8+8 root 2 = 16+8root 2
hence 8 root 2 can not be the answer.

16root 2 also not satisfy the condition. i dont understand something is wrong somewhere?

if length of equal sides is a ,perimeter is
2a+aV2=aV2*(V2+1)=16+16V2=16(V2+1)

hence aV2=16

length of hypotenuse is 16
ans option B
