sum of resistors that r in sereis across A point
= 2+2+2+2
=8
similarly sum of resistors acroos point b
=2+2+2+2
=8
sum of resitors that r in b/w a and b point which r in parallel combination so...
1/2+1/2+1/2+1/2
=2
now add all
8+8+2
=18.

kanikagoyal:
2+2+2×r/2+r = r
8+4r +2r = 2r +square of r
square of r- 4r-8 = 0
(r- 2)*square =12
r = 2+ 2. root3
okk
may be it is correct
not may be
it is
could u mark me as brainleist
