can you help me solve this please

Problem 4 (25 marks) The rigid, massless, 120 bent gate shown below (not to scale) has width d=2.0m (into the page) and holds a volume of water (density =1000kg/m2 ). The gate has dimensions a=1.0m,b=2.5m,c=1.5m, and the angles indicated in the diagram. Above the water, and also to the left of and below the gate, is air at atmospheric pressure. The gate is held closed by a vertical force, F, applied at the point shown. (a) Draw a free body diagram of the gate. In the drawing, show pressure forces as distributed loads in gage units. Label point forces with variable names. Label the vertices of distributed loads with expressions for the local pressure in terms of variables given in the problem. (b) Calculate the force, F, required to hold the gate shut
