Using Roboblockly to Solve Simple Mathematical Expressions
Problem Statement:
Use the preplaced blocks to set a variable to the sum of the square root of 225 + 5. Drive the robot the distance of the solution by inserting a variable block for the value of driveDistance. Print out the answer in the following format: variable is 20 which is the sum of the sqrt of 225 plus 5. You will need to use the Math, Text and Variable tabs to find all the missing blocks.
```/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
double variable;
CLinkbotI robot;
double radius = 1.75;

variable = sqrt(225) + 5;
robot.driveDistance(variable, radius);
