Question

Question 1: Score 0/1 A cross section AB of a square plate is covering a hole in a section of a wall shown below. Taking the density of the fluid to be 1025 kg.m3, h, 3 m, h2 2.5 m and w = 1.5 m. Calculate the magnitude of the reactions normal to the wall surface that would be required to maintain the equilibrium of the plate. h1 h2 B/ RA = Correct response Your response 66.4764 kN 163.9+1 kN Grade: 0/1.0 Ra Your response Correct response 199.6+1 kN Grade: 0/1.0

Please note the correct response, I don't know how to get to these thank you
