Geometry: Area of a Triangle in Coordinate Plane
Problem Statement:
Add driveDistance() blocks before the preplaced blocks to draw the triangle represented by points (3,0), (9,0), and (4,5). Then answer a prompt about the shape's area.
```/* Code generated by RoboBlockly v2.0 */
double Area;
double radius = 1.75;
double trackwidth = 3.69;

robot.traceOff();
robot.drivexyTo(3, 0, radius, trackwidth);
robot.traceOn();
robot.drivexyTo(9, 0, radius, trackwidth);
robot.drivexyTo(4, 5, radius, trackwidth);
robot.drivexyTo(3, 0, radius, trackwidth);
Area = 15;
