A triangle and a parallelogram are constructed on the same base such that their areas are equal. If the altitude of the parallelogram is 100 m , then the altitude of the triangle is	Choose one.
A) 10√2 m B) 100 m C) 100√2 m D) 200 m E) None
Solution   Let the altitude of the triangle be hïand base of each be b.   Then , (½ ×b× h1) where h2 = 100 m.   = h1 = 2h2   = ( 2 x 100) m   = 200 m.   Answer 200 m
