Question 1:find the area enclosed by the curve y = (x^2 - 3x) and
the line y = x

Question 2: Find the area of the region in the first quadrant enclosed by the curve y = (x^2), the y axis and the line 2x + y = 8.

Question 3: two curves y^2 = 4x and x^2 = 4y
intersect at point a (0,0) and point b (4,4)
Find the area of the shaded region enclosed by the two curves.


thanks for your help i cant seem to eork these out i keep getting the wrong answers.

question1 ans =10 and 2/3
question2 ans =9 and 1/3
question3 ans = 5 and 1/3

cheers :)
