Calculating Size and Scale

The images below are organisms that differ in size and scale. The images are as they would be viewed through a microscope equipped with an ocular micrometer. The micrometer has been calibrated according to $\frac{m}{o}$cular division as follows:

$\backslash$table$[[$Total mag,$\frac{m}{d}iv.],[40$X$,25\frac{m}{?}$ div.$],[100$X$,10\frac{m}{?}$ div.$],[400$X$,2\mathrm{.}5\frac{m}{d}iv.],[1000$X$,1\mathrm{.}0\frac{m}{d}iv.]]$

The organisms on the left are green algae of the genus Netrium. Total magnification $100$X$.$

What is the width of the cells in microns $($micrometer scale$)?$

What is the length of the cells in microns? $q,$

Using a ruler, what is the length of the image of the cells in mm : $$

What is the "scale" of the image?

$q,$

The image on the left is human blood cells. The smaller cells are erythrocytes, and the larger cell is a monocyte. Total magnification $400$X$.$

What is the diameter of the erythrocytes in microns? $$

What is the diameter of the monocyte in microns? $$

What is the scale of the image? $$
