A composite plate comprises a triangular area (1) and rectangular area (2) as shown in the figure. The triangular plate experiences forces due to the liquids of densities rho_(1) and the rectangular plate experiences the force due to liquid of density rho_(2) . Find the hydrostatic forces on (a) area 1 , (b) area 2 , (c) total composite area of the plate. Assume rho_(1)=rho and rho_(2)=2rho .
