Almost certain the area of that triangle one is 36.9. 12.3*0.5*6. I got it wrong :biggrin: multiplied by the x coord (5) instead of the y one (6).
If that was c1 then I'm ****ed for c2
For Q7 I remember u were given f'(x) and u need to use integration to find f(x)... I substitute (4,-8) in and I got C=40 or something like that..

Q2 was 1/8 not 1/16. You probably simplified it wrong.
