Answer:
1. To conduct Sports Day activities, in D your rectangular shaped school ground ABCD, lines have been drawn with chalk powder at a Il distance of Im each. 100 flower pots have been placed at a distance of Im from each other along AD, as shown in Fig. 7.12. Niharika runs th the distance AD on the 2nd line and posts a green flag. Preet runstht the distance AD on the eighth line and posts a red flag. What is the distance between both the flags? If Rashmi has to post a blue flag exactly halfway between the line segment joining the two flags, where should she post her flag.
