Late to reply, but if you are still interested... I think they mean simply increases in size. One of the limitations on how large cells can grow is the surface area to volume ratio. The word ratio is the key.

I think I figured it out! so, I think: L2 = (L-y)2 + x2 L2-x2 = (L-y)2 (L2-x2)1/2 = L - y -(L2-x2)1/2 = - L + y L -(L2-x2)1/2 = y I think that's it! Having to crop a picture for this question made me focus only on the variables I needed in the diagram. I see the solution now is...

formula correction It should be: L2 = (L-y)2 + x2
