Question

Side of square is 16 cm then what is the length of hypotenuse?

Answer 1

Hypotenuse=Diagonal

Sides are equal of square

So,
let's assume

a=16cm
b=16cm
c=Hypotenuse

a²+b²=c²
16²+16²=c²
256+256=c²
512=c²
√512=c
16√2=c

Hypotenuse=16√2cm

Answer 2

All sides are equal I.e.16cm
vertex angle =90degree
By Pythagoras theory
H^2=B^2+P^2
H^2=16^2+16^2
H^2=256+256
H=√512
H=16√2
H=22.62cm
