Area of a triangle having base 6cm and altitude 8cm is:
Two triangles have equal area of 24cm2 and stand on the same base of 6 cm, if the distance PQ (on base) between their altitudes is equal to the length of one of the altitude. Then the area of quadrilateral formed by the altitudes and the base PQ is equal to:
Here AB ∥ CD. If the altitude of △ACD is 6 cm and CD is 8 cm then the area of △BCD is:
