A rectangle has 4 right angles, so the diagonal
\n" ); document.write( "makes a right triangle.
\n" ); document.write( "Let \"+x+\" = the unknown side of the rectangle.
\n" ); document.write( "One of the known right triangles has sides in the ratio:
\n" ); document.write( "3 - 4 - 5
\n" ); document.write( "The sides are in the same ratio:
\n" ); document.write( "x/20 - 80/20 - 1000/20 same ratios as: 3 - 4 - 5
\n" ); document.write( "So I can say:
\n" ); document.write( "\"+x+=+60+\" so that \"+x%2F20+=+3+\"
\n" ); document.write( "dimensions are 60m x 80m x 1000m
\n" ); document.write( "
\n" ); document.write( "
\n" );
