The area of a rectangle is
\n" ); document.write( "\"+A+=+h%2Aw+\"
\n" ); document.write( "where \"+A+\" = area in ft2
\n" ); document.write( "\"+h+\" = height in ft
\n" ); document.write( "\"+w+\" = width in ft
\n" ); document.write( "-------------------
\n" ); document.write( "I'll call the length of the runway \"+h+\", so
\n" ); document.write( "The area of the runway is \"+A+\", so
\n" ); document.write( "\"+A+=+1813500+\" ft
\n" ); document.write( "The width of the runway is:
\n" ); document.write( "\"+w+=+150+\" ft
\n" ); document.write( "------------------
\n" ); document.write( "\"+A+=+h%2Aw+\"
\n" ); document.write( "\"+1813500+=+h%2A150+\"
\n" ); document.write( "Divide both sides by \"+150+\"
\n" ); document.write( "\"+h+=+1813500%2F150+\"
\n" ); document.write( "\"+h+=+12090+\" ft
\n" ); document.write( "The length of the runway is 12,090 ft
\n" ); document.write( "
\n" );
