we can simply find the component of the vector :
for OA - Rcos0=R ( as cos 0 = 1 ) 
for OB - Rcos45=R/√2 ( as cos 45 = 1/√2 )
for OC - Rcos45=R/√2 ( as cos 45 = 1/√2 )
Adding all we get - R/√2 + R/√2 + R = 2R/√2 + R , which on further simplification gives √2R + R = 
R(√2+1) , hence the required answer.
