The figure can be understood in either of two ways:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(*) A rectangle of 92 x 40 from which a trapezoid of bases 5 and 92 and height 35 has been removed. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(*) Two congruent trapezoids and one square; the trapezoids having bases 5 and 40 and of \"height\" \"%2892-5%29%2F2\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Choose the viewpoint you like and find the perimeter. The slanted segments are the trickier part. You already have these known sides: 40, 92, 40(again), and 5. Next, project a segment from the lower 5 foot segment so it intersects each of the 40 foot sides and identify two congruent RIGHT triangles. The slanted segment is a hypotenuse. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Each triangle is of legs \"%2840-5%29=35\", and \"%2892-5%29%2F2=87%2F2\".
\n" ); document.write( "Pythagorean Theorem will give you the hypotenuse distance.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"s=sqrt%2835%5E2%2B%2887%2F2%29%5E2%29\", and the figure has two of these.
\n" ); document.write( "
\n" );
