Starting with the formula for the area of a trapezoid:
\n" ); document.write( "\"A+=+%28b1+%2B+b2%29h%2F2\" substitute:
\n" ); document.write( "A = 224
\n" ); document.write( "h = 16
\n" ); document.write( "b1 = 20
\n" ); document.write( "Solve for b2.\r
\n" ); document.write( "\n" ); document.write( "\"A+=+%28b1%2Bb2%29h%2F2\" Multiply both sides of the equation by 2.
\n" ); document.write( "\"2A+=+%28b1%2Bb2%29h\" Divide both sides by h.
\n" ); document.write( "\"2A%2Fh+=+b1%2Bb2\" Subtract b1 from both sides.
\n" ); document.write( "\"%282A%2Fh%29-b1+=+b2\" Substitute the given values of A=224 h=16, b1=20.
\n" ); document.write( "\"2%28224%29%2F16+-+20+=+b2\"
\n" ); document.write( "\"28+-+20+=+b2\"
\n" ); document.write( "\"b2+=+8\"\r
\n" ); document.write( "\n" ); document.write( "The other base is 8 meters.
\n" ); document.write( "
\n" );
