You can put this solution on YOUR website!
Let +x+ = distance from bottom of mirror to floor
+x%2F2+ = distance from top of mirror to ceiling
+x%2F2+%2B+28.25+%2B+x++=+91.25+
+%283%2F2%29%2Ax+=+63+
+x+=+%282%2F3%29%2A63+
+x+=+2%2A21+
+x+=+42+
The distance from bottom of mirror to floor is 42"
--------------------
check:
+x%2F2+%2B+28.25+%2B+x++=+91.25+
+21+%2B+28.25+%2B+42++=+91.25+
+91.25+=+91.25+
OK
