If no distance is given, such dimension shall be determined by the use of the scale shown on said zoning map.

4.3.4. Where a district boundary line, as appearing on the zoning map, divides a lot in single ownership at the time of this enactment, the district requirements for the least restricted portion of such lot shall be deemed to apply to the whole thereof, provided that such extensions shall not include any part of such a lot more than 35 feet beyond the district boundary line.
