Hi, I'm not sure if I made an careless mistakes but the general approach to solve this question is written here. Hope it helps.

The answer for (b) is 23x+8y-20=0 and the answer for (c) is 1.95units square though...

As for part (c) perhaps I made some mistake in the calculation but the basic idea is finding the area under the curve by integration (from x=0 to x=3), then subtracting the area of the triangle under the straight line.

Hi, change the "3(ln10)" to "3(ln4)" and you should get the answer. Careless mistake, sorry!
