O is a point inside the triangle MNP.
UV is a line drawn through O parallel to MP which intersects MN at U and NP at V.
RQ is a line drawn through O parallel to MN which intersects MP at R and NP at Q.
ST is a line drawn through O parallel to NP which intersects MN at S and MP at T.
The respective areas of triangles ROT, UOS and QOV are 4, 9 and 49
