Final answer:
There is a mix-up in provided details; the question asks about the Old Minnehaha County Jail, but the associated reference is for an old slave quarter. Exact dimensions of the jail would require research into historical records or architectural documentation.
Step-by-step explanation:
The question pertains to the dimensions of the extant rear section of the historical Old Minnehaha County Jail. However, there appears to be a mix-up with the details provided, as the reference given is associated with a photograph of an old slave quarter rather than the jail in question.
The photograph is from the 1930s and depicts the Old Quarters located at Wisconsin Avenue & State Route 193 in Bethesda, Montgomery County, MD. The image in question was taken by Thomas Waterman and is reported to have no known copyright restrictions according to LibreTexts™.
Without specific historical records or architectural plans, determining the exact dimensions of the rear section of the Old Minnehaha County Jail would require further research into historical documentation or archaeological studies related to the structure.
If the student is specifically interested in the Old Minnehaha County Jail, then it would be best to seek out data from local archives, historical societies, or records pertaining to the jail's specifications. This would provide accurate information on the jail's dimensions rather than relying on information about a different historical building.
