1. So firstly sorry for the horizontalness of the pic and the messy handwriting...

Am I doing the right thing? And what should I do with those two values of W?

I can't access the answers for this so I'm just wondering if I am doing it right?

So basically you have and (and similar for y min and max).

Then to get the biggest value of w, you want biggest value of x / smallest value of y ( can you see why?)

So - can you then see what you need to do for ?

so to a suitable degree of accuracy means the biggest value possible?

Sorry, just properly read your question, you'd already done that bit! Uhm, basically, to a suitable degree of accuracy means the value of that both and round off to the same thing.

So, ask yourself is is suitable by checking whether rounds to that. Obviously not.

Is suitable? Does both and round off to that (to 3 d.p)? Obviously not.

What about (2 d.p). Do both values of round off to that? If so, then that's the suitable degree, other wise try once decimal place and then one significant figure, etc...
