Question. 10
10. Ratio of area of \( \triangle MNO \) to the area of parallelogram MNOP in the same figure 9.17 is
(a)
(a) 2 : 3
(b)
(b) 1 : 1
(c)
(c) 1 : 2
(d)
(d) 2 : 1
Detailed Answer with Explanation:
Area of parallelogram MNOP = base × height = NO × OQ.
Area of triangle MNO = \( \tfrac{1}{2} NO \times OQ \).
So, ratio = (1/2 NO × OQ) : (NO × OQ) = 1 : 2.
