I think they are assuming the photo is from directly above,
\n" ); document.write( "and there is no distortion of the lengths
\n" ); document.write( "-----------------
\n" ); document.write( "I can use proportions:
\n" ); document.write( "\"+3%2F5+=+150%2Fa+\"
\n" ); document.write( "\"+3a+=+5%2A150+\"
\n" ); document.write( "\"+3a+=+750+\"
\n" ); document.write( "\"+a+=+250+\" m
\n" ); document.write( "-------------------
\n" ); document.write( "\"+3%2F9+=+150%2Fb+\"
\n" ); document.write( "\"+1%2F3+=+150%2Fb+\"
\n" ); document.write( "\"+b+=+450+\"
\n" ); document.write( "-------------------
\n" ); document.write( "The longest side is 450 m
\n" ); document.write( "The middle length is 250 m
\n" ); document.write( "----------------------------
\n" ); document.write( "check:
\n" ); document.write( "\"+5%2F9+=+250%2F450+\"
\n" ); document.write( "\"+5%2F9+=+50%2F90+\"
\n" ); document.write( "\"+5%2F9+=+5%2F9+\"
\n" ); document.write( "OK
\n" ); document.write( "
\n" ); document.write( "
