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`.
