You can put this solution on YOUR website!
Let x- be the width\r
\n" ); document.write( "\n" ); document.write( "In finding the Perimeter, we use the formula
\n" ); document.write( "P=2length+2width\r
\n" ); document.write( "\n" ); document.write( "So,
\n" ); document.write( "240 = 2(99) + 2x
\n" ); document.write( "240 = 198 + 2x
\n" ); document.write( "42 = 2x
\n" ); document.write( "21 = x\r
\n" ); document.write( "\n" ); document.write( "So the width should be 21 cm, to have a length of 99 cm and a perimeter of 240 cm.\r
\n" ); document.write( "\n" ); document.write( "Hope that helps! :)
