Find the length of the other base of a trapezoid whose height is 16 metres, first base is 20, and whose area is 224 square metres.
\n" ); document.write( "Starting with the formula for the area of a trapezoid with bases, b1 and b2, and height,h:
\n" ); document.write( "\"A+=+%28%28b1%2Bb2%29%2F2%29h\" where: h = 16m, b1 = 20m, and A = 224 sq.m, we'll solve for b2.\r
\n" ); document.write( "\n" ); document.write( "\"224+=+%28%2820%2Bb2%29%2F2%2916\" Divide both sides by 16.
\n" ); document.write( "\"14+=+%2820%2Bb2%29%2F2\" Multiply both sides by 2.
\n" ); document.write( "\"28+=+20%2Bb2\" Subtract 20 from both sides.
\n" ); document.write( "\"8+=+b2\"\r
\n" ); document.write( "\n" ); document.write( "The length of the other base is 8 metres.\r
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "\"%28%2820%2B8%29%2F2%2916+=+%2814%29%2816%29\" = \"224\"
\n" ); document.write( "
\n" );
