Calculate The Area & Perameter Of A Ractangle And The Area & Circumference Of The Circle

/* Calculate The Area & Perimeter Of A Rectangle
   And The Area & Circumference Of The Circle */

/* The Length And Breadth Of A Rectangle And Radius Of A Circle Are Input Through
   The Keyboard. Write A Program To Calculate The Area & Perimeter Of A Rectangle
   And The Circumference Of The Circle */
