You would divide it into shapes that you already know, like squares, rectangles and triangles. Find the area of each shape and add them together
The plane PRS passes through the points P, R and S. So it contains the line RS. Also the plane QRS passes through the points Q, R and S. So it contains the line RS as well. Since both the planes contain the line RS, the line RS must be the intersection of plane PRS and QRS
