here is my code
boolean first = true;
boolean second = false;
float x1, y1, x2, y2;
void setup() {
size(300, 300);
background(255);
textSize(24);
fill(0);
textAlign(CENTER);
}
void draw() {
background(255);
if ( first == false) {
//fill(0,0,250);
rect(x1, y1, mouseX, mouseY);
}
else if (second == true) {
fill(255, 0, 0);
rect(x1, y1, x2, y2);
}
}
void mousePressed() {
background(255);
second = true;
x1 = mouseX;
y1 = mouseY;
//record the first corner
first = false;

//rect(x1,y1,x2,y2);
x2=0;
y2=0;
text(round(area(x1, y1, x2, y2)), width/2, height/2);
background(255);
}
float area(float x1, float y1, float x2, float y2) {
float a1 = (x2-x1);
float a2 = (y2-y1);
return sqrt(a1*a1+a2*a2);
}
