A quadrilateral has 4 vertices and we have 9 points.. (5+4)
Select two from 5(line l) = 5c2 = 10
Select two from 4(line m) = 4c2 = 6
10*6 = 60

C

P.s = there are 9 points, not 8*...

=>

To create a quadrilateral, we should choose \(2\) points out of \(5\) points on line \(l,\) and \(2\) points out of \(4\) points on the line m and connect them.

Then we have 5C2*4C2 = \([\frac{(5*4)}{(1*2)}][\frac{(4*3)}{(1*2)}] = 10*6 = 60.\)

Therefore, C is the answer.
Answer: C

Quadrilaterals can be formed by choosing 2 points on line l and 2 points on line m

Number of ways = 5C2 * 4C2 = 10 * 6 = 60

IMO C
