You are more likely to get help if you post pictures rather than expecting helpers to download files.
Also, include relevant equations and your attempt - typed - not images of messy handwriting.

As a scientist, it is important to always verify the accuracy of your calculations. In this case, it would be helpful to provide more information about your solution, such as the equations and assumptions used, in order to determine if the torque was calculated correctly.

One possible approach to calculating the torque on the dam about the origin due to the pressure force of the fluid is to first calculate the force acting on each small element of the dam. This can be done using the equation for pressure force, dF = P*dA, where P is the pressure and dA is the area of the small element. Then, the torque can be calculated by summing up the torques from each small element, taking into account the distance from the origin for each element.

It is also important to note that the torque due to the pressure force of the fluid may not be the only torque acting on the dam. Other factors such as the weight of the dam and any external forces must also be considered in order to accurately determine the overall torque on the dam.
