Answer:
5 feets
Explanation:
Give the field dimension :
70 feets by 25 feets
The largest possible size if field is divided into squares :
Obtain the greatest common factor of the length and width :
Factors of 70 : 1, 2, 5,7,14, 10, 35
Factors of 25 : 1, 5, 25
The greatest common factor = 5
Hence, the largest possible square plot will have a side length of 5 feets
