I'll convert everything to inches
\n" ); document.write( " $\"+20%2A12+=+240+\"$ in
\n" ); document.write( "6'2\" = $\"+6%2A12+%2B+2+=+74+\"$ in
\n" ); document.write( " $\"+3%2A12+=+36+\"$ in
\n" ); document.write( "Let $\"+x+\"$ = the height of the building in inches
\n" ); document.write( " $\"+x+%2F+240+=+74%2F36+\"$
\n" ); document.write( " $\"+x%2F240+=+37%2F18+\"$
\n" ); document.write( "Multiply both sides by $\"+120%2A18+\"$
\n" ); document.write( " $\"+9x+=+120%2A37+\"$
\n" ); document.write( " $\"+9x+=+4440+\"$
\n" ); document.write( " $\"+x+=+493.333+\"$ in
\n" ); document.write( "In feet this is:
\n" ); document.write( " $\"+493.333%2F12+=+41.111+\"$ ft
