Let's go through the answer choices one by one:
A. False. The line segment contains more than just the endpoints
B. False. There are points in this description that extend beyond the endpoints. If this was a line instead of a segment, then choice B would be the answer
C. True. This is the answer. Though your teacher should have added "collinear" to the sentence to make it clear that the points are between M and N, and also collinear to M and N. All of these points form the line segment MN
D. False. That would be the perpendicular bisector of MN

So once again, the final answer is choice C
The longer sides are 20 kilometers, and the shorter sides are 13 kilometers.
(Length times width equals 260, and 20 times 2 plus 13 times 2 is 66.)
2.50 would be 25% out of 100%
Five million four thousand three hundred in standard form is 5,004,300
