In 1st part, that is part (a), apply 1/2*b*h formula of triangle area for both triangles, then sum it up.( Triangles PQS and QRS separately ).
In 2nd part find area ACB, and ECD by 1/2*b*h formula. In triangle ACE apply Heron's formula to find area.
In 3rd part again apply 1/2*b*h formula In triangles BCD and ACD seprately to find areas then sum them up.
Hope this helps......
