concrete sections for a new building have the dimensions in meters and shapw shown in the figure. a)find the area of the face of the section superimposed on the rectangular coordinate system. The way i tried to solve this was to split it up into 2 integrals and add them together to get the area the integrals were integral from -5.5 to 0 of 1/3*sqrt(5+x)dx + integral from 0 to 5.5 of 1/3*sqrt(5-x)dx I tried the first part and got 2/9*(5+x)^(3/2) but when you evaluate it at -5.5 you end up taking the squareroot of a negative number. Did i do it completely wrong? or did i just make a simple mistake? any help would be appreciated.
