The vertices are at (0,10), (10,10),(5,5) and (0,5)
\n" ); document.write( "You need to find the area of the rectangle (0,10) (10,5) (0,5) and (5,5)\r
\n" ); document.write( "\n" ); document.write( "the lengths are 5, 5,5,5
\n" ); document.write( " so the area is 25
\n" ); document.write( "and the right triangle (10,5) ,(5,5) and (10,10) the right angle is at (10,5)
\n" ); document.write( "the two legs are length 5 and 5
\n" ); document.write( "area 1/2* 25
\n" ); document.write( "so together they are 25 +12.5=37.5 square units
\n" ); document.write( "
\n" );
