Geometry: Perimeter & Area of Basic Shapes in Coordinate Plane
Problem Statement:
Draw the triangle represented by points (3,0), (9,0), and (3,5). Calculate the area.
```/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
double area;
CLinkbotI robot;
double radius = 1.75;
double trackwidth = 3.6;

robot.traceOff();
robot.drivexyTo(3, 0, radius, trackwidth);
robot.traceOn();
robot.drivexyTo(9, 0, radius, trackwidth);
robot.drivexyTo(3, 5, radius, trackwidth);
robot.drivexyTo(3, 0, radius, trackwidth);
