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 the most appropriate option:
A) 200 m	B) 150 m	C) 148 m	D) 140 m	E) None of these
Explanation:   Let the triangle and parallelogram have common base b,   let the 200 mltitude of triangle is h1 and of parallelogram is h2(which is equal to 100 m), then   200 mrea of triangle =1/2∗b∗h1   200 mrea of rectangle =b∗h2   200 ms per question 1/2∗b∗h1=b∗h2   1/2∗b∗h1=b∗100   h1=100∗2=200m   Option 200 m
