Area of trapezoid = \"%28a%2Bb%29%2F2+%2A+h\"\r
\n" ); document.write( "\n" ); document.write( "\"69.6+=+%28%28a%2Bb%29%2F2%29+%2A8.7\"\r
\n" ); document.write( "\n" ); document.write( "solve a+b = 16\r
\n" ); document.write( "\n" ); document.write( "sum of legs = sum of bases\r
\n" ); document.write( "\n" ); document.write( "Perimeter = 16*2=32 in^2\r
\n" ); document.write( "\n" ); document.write( "
