Answer: i believe its 8
Step-by-step explanation:
i say 8 because 3x4 is 12 and so if bertha orignally had 4 and was given 4 she would have 8 and if su had 12 and gave away four she would also have 8
1 : 40 = 6 : 240
On the ground the fence would be 240 inches long
240 / 12 = 20 feet long fnce
Your question does not make sense unless you can estimate but the answer would be 20.625
Work:

The length of CD is 7-3=4.
