Question

Find the lenght of the side of
square if the
lenght of
its diagonal is
10 cm.​

Answer 1

let the sides be x.

then according to Pythagoras theorem,

x²+ x²= (diagonal)²

(diagonal)² = 2x²

diagonal= √2x ––––(1)

But we r given that diagonal=10 cm––––(2)

Adding (1) and (2),

√2x = 10 cm

x=10/√2 cm

x= 5√2 cm. (By rationalizing 10/√2)

Hence the side is 5√2 cm...
