Function Calculating the Area of a Rectangle Using a Function with a Return Value
/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
double area;
CLinkbotI robot;
double radius = 1.75;
double trackwidth = 3.69;
int count;

// Describe this function...
double rectangleArea(double width, double height) {
  robot.traceColor("#00FFFF", 3);
  count = 0;
  while(count < 2) {
    robot.driveDistance(height, radius);
    robot.turnRight(90, radius, trackwidth);
    robot.driveDistance(width, radius);
    robot.turnRight(90, radius, trackwidth);
    count = count + 1;
  }
  return width * height;
}

Problem Statement:

Use the function block to draw rectangle with an area of 36 square units. You will need to fill in variables needed to calculate the area of rectangle and assign values to the dimensions of your rectangle so the area equals 36 square units. Finally, you need to enter in a complete sentence that tells the user the area of their rectangle.
