How do I find the area of the region bounded by the graphs y = root x, y= x-2 and y= 1

I did the integral of root x minus 1 from 1 to 3 plus the integral of root x minus x plus 1 from 3 to 4. Apparently this is wrong, how should it be set up as?

I apologize for not entering it in a proper math format, I have no idea how to do so.
