\n" ); document.write( "\n" ); document.write( "        In the post b @HyperBrain, the basic formula and calculations are incorrect.\r
\n" ); document.write( "\n" ); document.write( "        The correct solution is in my post below.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Given the two bases a and b, and the height h of a trapezoid, the area is given by\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "        A = \"%28%28a%2Bb%29%2F2%29%2Ah\",\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so the area of the trapezoid you're given is   \"%28%2825%2B7%29%2F2%29%2A9\" = \"%2832%2F2%29%2A9\") = 16*9 = 144 sq. meters.\r
