Using Dilation to Create a Tent for a Bulldog
Problem Statement:
Johnny is going on a camping trip and he is taking his Bulldog Rosco with him. Johnny set up his triangular tent, but wants to put a smaller tent inside of his tent for Rosco to sleep in. Johnny decides to use geometry and create a dilation of his tent to use as a tent for Rosco. If Rosco is three times smaller than Johnny, what scale factor should Johnny use when creating a tent for his Bulldog Rosco? Run the program and input your answer.
/* Code generated by RoboBlockly v2.0 */
#include <chplot.h>
double scale_factor;
CPlot plot;

printf("What scale factor should Johnny use to construct the tent for his Bulldog? Input your answer as a decimal rounded to the nearest hundredth."+"\n");
scanf("%lf", &scale_factor);
plot.strokeColor("#6600cc");
plot.fillColor("blue");
plot.triangle(0, 12 * scale_factor, -6 * scale_factor, -6 * scale_factor, 6 * scale_factor, -6 * scale_factor);

plot.label(PLOT_AXIS_XY, "");
plot.grid(PLOT_OFF);
