Question

U know in ( 1+2 ) i can be converted
to Cartesian as (1,2)
so find distance between
(0,0)( in(1,2) ) that will come ( sqrt{5} )
... ก०
equal to hexagon radius....
therefore side ( =sqrt{5} )
perimeter ( =6 sqrt{5} )

# statements 52. If centre of a regular hexagon is at origin and one of the vertex on Argand diagram is 1 + 2i, then its perimeter is (1) 615 31 (2) 415 (3) 602 (4) 215
