a dorm room at a college your sister is considering seems small. The room is rectangular and has a perimeter of 42 feet. The room is 4 feet longer than it is wide. what are the dimensions of the room
\n" ); document.write( "The formula for the perimeter of a rectangle is \"P=2L%2B2W\", P=perimeter, L=length, and W=width
\n" ); document.write( "Let width =x
\n" ); document.write( "Then length is: x+4
\n" ); document.write( "P is: 42
\n" ); document.write( "42=2(x+4)+2(x)
\n" ); document.write( "42=2x+8+2x
\n" ); document.write( "42=4x+8
\n" ); document.write( "42-8=4x+8-8
\n" ); document.write( "34=4x
\n" ); document.write( "34/4=4x/4
\n" ); document.write( "17/2=x
\n" ); document.write( "8 1/2 =x
\n" ); document.write( "The width x=8 1/2 ft
\n" ); document.write( "The length x+4=8 1/2 +4= 12 1/2 ft
\n" ); document.write( "Happy Calculating!!! \n" ); document.write( "
\n" );
