Refer the working first, they have given us keh 1 micrometer div is 0.01mm and look i can see that 10 micrometer div(bigger ones) equals to 42 eye piece div(smaller ones), so i'll work out that what is the length of 10 micrometer div. and the length is equal to 42 eyepiece div, so for one eyepiece div, i haveto divide the length with 42 and for step 2, we need to change it to micrometers as our anwer in step 1 is in mm. hope u get that
Awesome !!(y)
Thnx !!:)

Here you see...
L is slerenchyma, m is phloem , n is cambium and p is xylem...You have to compare their length with the stage micrometer given in the figure (i.e -> 30 divisions from r to k(actually 9 cm from ruler)) i got l m n p as 5 ,5 ,5 ,15 total = 30
then make diagram accordingly to the given figure :) (Y)
