Isosceles right triangle

If the square of the hypotenuse of an isosceles right triangle is 128 cm2, find the length of each side.

Correct answer:

a =  11.3137 cm
b =  8 cm
c =  8 cm

Step-by-step explanation:

S1=128 cm2 S1 = a2  a=S1=128=8 2=11.3137 cm
b=c b2+c2 = a2 2b2 = a2  b=a/2=11.3137/2=8 cm
c=b=8=8 cm
