We are getting 21cm because graph drawn is wrong. In y axis it goes as 10,20,30,.... and in x axis it goes as 26,28,30,.... The Scale is not proportional. So, If both x and y axis is taken as 10,20,30,.. Then we will get distances equal to 2f where bisector intersects on both x and y axis. So we will get f like this. (2f+2f)/4= 4f/4= f

You should flip the lens to check the difference of the point of observer. This was a great study though.👍
