You need to know radius of curvature. f = R/2
OR use v :- distance of image from mirror and u:- distance of object from mirror.
1/f = 1/v + 1/u

I hope it helps :)
wrong answer
How is it wrong?
I am currently studying this chapter and I solved so many numericals using these formulas to find out focal length. So I think YOU are the one who's wrong.
sorry it is correct answer
Ok......... no problem.

materials required for finding focal length of concave mirror =>>>>>
1.) using first method you required radius of curvature of concave mirror.
✳f=2R
2.) in second method you required, distance from object and distance from image.
✳1/f=1/v+1/u
