A triangle XYZ has sidės XY = XZ 41 cm and YZ = 18 cm. The triangle PQR inscribed in the triangle XYZ so that PQ is parallel to YZ. R is the midpoint of YZ. Given that PQ =s cm, the perpendicular height of R from PQ is h cm and the area c triangle POR is A cm². 41 cm R 18 cm (1) Express h in terms of s.
