Suppose, ABCD is a square in the Figure below. Here, you have a ultrasonic sonar sensor at the center O, of the circle in ABCD. Now, you have to measure the Area of the square and circle through Arduino Sketch. Please explain the calculation procedure of that sensor briefly. [Note: Area of a circle is measured by the formula r2. The figure is drawn to scale.]
