Hi, i am having difficulty with a question because i cannot seem to get the right answer. i don't think i am far off i just know i go wrong somwhere and if you could point that out it would be great. the question is attatched. for the first part i find the equations of the lines of the two sides starting from d. then subtract them to find w (=Xright-Xleft). using double integration i find the area by
A=∫∫dA where limits firstly are X=Xright, X=Xleft and then S=h and S=0. My problem is on part C i cannot get the correct answer which means i have gone somewhere wrong further up, most likely at either the limits I am using or for S or finding w. I am meant to use double integration for these questions and Sc=As|o /A and ***|c= ***|o - A*Sc^2.
Any comments are appreciated, thanks
