The perimeter of a rectangle is the sum of all of its sides. \n" ); document.write( "Since a rectangle has four sides, the standard equation is: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "However, our problem tells us the length is 4 times the width, so let: \n" ); document.write( "x = width \n" ); document.write( "4x = lenght\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Therefore, our equation becomes: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Each width measures 20 feet, each lenght measures 20 feet x 4 = 80 feet.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Check: |
