Lets say Polygon A has length 14 and width 6.
\n" ); document.write( "Polygon B has length 20 and width x. x is the unknown and we need to evaluate it.\r
\n" ); document.write( "\n" ); document.write( "In case of two similar polygons the ratio of lengths of the two polygons should be equal to the ratio of their widths.\r
\n" ); document.write( "\n" ); document.write( "The ratio of lengths of the two polygons (A:B) is 14:20. When simplified this ratio becomes 7:10. \r
\n" ); document.write( "\n" ); document.write( "The ratio of widths of A to B is 6:x\r
\n" ); document.write( "\n" ); document.write( "Now since the two polygons are similar, therefore \"7%2F10+=+6%2Fx\"\r
\n" ); document.write( "\n" ); document.write( "That is \"7%2F10+=+6%2Fx\"
\n" ); document.write( " => \"7%2Ax+=+6%2A10\"
\n" ); document.write( " => \"x+=+60%2F7+=+8.57\"\r
\n" ); document.write( "\n" ); document.write( "Therefore the width of the polygon B is 8.57
\n" ); document.write( "
\n" );
