Clinometer is a tool that is used to measure the angle of elevation. We can use the clinometer to measure the height of tall things that you can't possibly reach. With the help of a clinometer, Harish measured the angle of elevation of the roof of a building from a point $P$ on the ground as $45^{\circ }$. On the same wall, at some height below the top, there was a society logo, whose angle of elevation from the same point $P$ was measured as $30^{\circ }$. The point $P$ is at a distance of $24$ m from the base of the building. Based on the above information, answer the following questions.
