Could someone please explain this in details?

Goal: Determine the marginal densities fy(y) and fx(x) for the joint uniform pdf of X & Y random variables over the area given by: 0 X O 1 and compare those the marginal densities fy(y) and fx(x) for the joint uniform pdf of X & Y random variables over the area given by: O 2 X OSuhmittal Requirements: a.) Provide all four marginal densities, and b.) Provide observations on the results
