Length of the perpendicular = 3
Length of the hypotenuse = 6

The value of ''
".

 

Using Pythagoras theorem, we have 
 ( Perpendicular )² + ( Base )² = (Hypotenuse)²
 ( 3 )² + 
 = ( 6 )²
 9 + 
 = 36
 
 = 36 - 9
 
 = 27
 
 = 

Therefore, the length of the missing side 
 is 
.

 ( 3 )² + ( √27 )² = ( 6 )²
 9 + 27 = 36
 36 = 36
 L. H. S. = R. H. S. 
Hence verified. ✔
