So let's say that the lenghth of Dc is 10 and then it follows that each point is 2.
The base of triangle NPS is comprised of 4 points inclusive so the length must be 6.
The triangle QMC is also comprised of 4 points which gives us the same base: 6.
Now we need to find the height. We can draw a height for triangle NPS which would be equal to the wide of the rectangle.
For triangle QMC we can draw a height from the line DC to the point M for example and it would have the same wide as the rectangle.
Therefore C of I am right
If nothing is indicated regarding point M and N lying on segment AB, can we assume according to the graphic that they are effectively on the segment ???

We know if two triangle stands on base of same length and enclosed within two parallel lines than triangles are equal.hnsere both triangles have same base length.
So ans is C
So ans is C
