calculate for the area of a rectangle,
\n" ); document.write( " knowing that the sum of the base and height measure 123
\n" ); document.write( "b + h = 123
\n" ); document.write( ":
\n" ); document.write( "the base is 1 / 2 of the height.
\n" ); document.write( "b = .5h
\n" ); document.write( ":
\n" ); document.write( "replace b with .5h in the 1st equation
\n" ); document.write( ".5h + h = 123
\n" ); document.write( "1.5h = 123
\n" ); document.write( "h = \"123%2F1.5\"
\n" ); document.write( "h = 82 units is the height
\n" ); document.write( "then
\n" ); document.write( "b = .5(82)
\n" ); document.write( "b = 41 units is the base
\n" ); document.write( ";
\n" ); document.write( "Find the area
\n" ); document.write( "A = 41 * 82
\n" ); document.write( "A = 3362 square units
\n" ); document.write( "
\n" );
