Resultant of two vectors r=[a2+ b2+ 2abcostheta]1/2
where a,b: magnitude of vectors , theta: angle between the vectors
Here , resultant r=[122 + 242 + 2(12)(24)cos90 ]½
                               = (144+576+0)1/2
                               = 7201/2
                                     
=26.833
Ans = 26.833
