Question

If the diagonal of a square is 13 cm then find

its side

---- Let PQRS be given square .Let the side of

the square be x cm



In △ SPQ,

∠

SPQ=90° (Angle of a square)

By Pythagoras theorem

SQ2= +



∴ =x2+x2

∴ 2x2=

∴

x2=

Taking square root both sides,

∴

x=

w

here x gives us the side of a square.​
