Start with the area of a triangle:
\n" ); document.write( "\"A+=+%281%2F2%29b%2Ah\" Substitute \"A+=+625\" and \"b+=+h%2F2\"
\n" ); document.write( "\"625+=+%281%2F2%29%28h%2F2%29%28h%29\" Simplify.
\n" ); document.write( "\"625+=+h%5E2%2F4\" Multiply both sides by 4.
\n" ); document.write( "\"2500+=+h%5E2\" Take the square root of both sides.
\n" ); document.write( "\"50+=+h\"
\n" ); document.write( "The length of the altitude is 50 inches.
\n" ); document.write( "
\n" );
