a rectangle has a perimeter of 80 feet, its length is 8 feet more than the width.
\n" ); document.write( " What is the length and the width.
\n" ); document.write( ":
\n" ); document.write( "The perimeter:
\n" ); document.write( "2L + 2W = 80
\n" ); document.write( "simplify, divide by 2
\n" ); document.write( "L + W = 40
\n" ); document.write( ":
\n" ); document.write( "It says,\"its length is 8 feet more than the width\"; therefore:
\n" ); document.write( "L = W + 8
\n" ); document.write( ";
\n" ); document.write( "Replace L with (W+8) in the 1st simplified equation
\n" ); document.write( "(W+8) + W = 40
\n" ); document.write( "2W = 40 - 8
\n" ); document.write( "2W = 32
\n" ); document.write( "W = \"32%2F2\"
\n" ); document.write( "W = 16 ft is the width:
\n" ); document.write( ":
\n" ); document.write( "I'm going to let you find the length, then check the solutions in the perimeter equation. \n" ); document.write( "
\n" );
