Have you plotted the points? Desmos is a graphing program you can download. Or you could use a graphics calculator. Or you could use Excel.

I can't find the formula to represent the relationship between l and P in question b/,
You are being asked to derive that formula by investigating the plotted graph from the given set of data.

I've tried it as well, got all the points. i tried y=0.2√x an it kinda fits into the points

Now put that (y=0.2 * √x) in terms of 'l' and 'P'
