Crowd Control


In an effort to keep people and the media away from a crime scene, police section off an area using police tape.

Your team has discovered that you only have 12m of police tape left. If you use the front wall (blackboard wall) as 1 side, what is the largest possible rectangular area your team can section off? What are the dimensions of this rectangle?

Draw the rectangle on a coordinate grid with the bottom left corner of the rectangle at the origin. Use a scale of 5cm = 1m.

  1. Plot the point A as the impact point of the murder.
  2. Find the distance from each corner of the roped area to the point of impact.
  3. Determine the exact distance from the blackboard wall to the point of impact.
