Geometry. The length of a rectangular playing field is 5 ft less than twice its width.
\n" ); document.write( "If the perimeter of the playing field is 230 ft, find the length and width of the field.
\n" ); document.write( ":
\n" ); document.write( "The formula for the perimeter of a rectangle is \"highlight%28P=2W%2B2L%29\", p=perimeter, W=width, L=lenght
\n" ); document.write( ":
\n" ); document.write( "Let width (W)=W
\n" ); document.write( "Then lenght (L)=2W-5
\n" ); document.write( "P=230 ft
\n" ); document.write( ":
\n" ); document.write( "Problem to solve:
\n" ); document.write( "230=2W+2(2W-5)
\n" ); document.write( "230=2W+4W-10
\n" ); document.write( "230=6W-10
\n" ); document.write( "230+10=6W-10+10
\n" ); document.write( "240=6W
\n" ); document.write( "240/6=6W/6
\n" ); document.write( "40=W
\n" ); document.write( ":
\n" ); document.write( "W=40 ft
\n" ); document.write( "L=2w-5=2(40)-5=80-5=75 ft
\n" ); document.write( ":
\n" ); document.write( "Check:
\n" ); document.write( "230=2(40)+2(75) ?
\n" ); document.write( "230=80+150 ?
\n" ); document.write( "230=230 !!! Looks good.
\n" ); document.write( "Happy Calculating!!! \n" ); document.write( "
