A)
Length of the rectangular garden = 120 m and breadth = 80 m
There is path of uniform width of 3.5 m all around the garden and the rest of the part is covered with grass.
So, Length of the portion covered by grass = 120 - (3.5 + 3.5)
= 120 - 7
= 113 m
And, Breadth of the portion covered by grass = 80 - (3.5 + 3.5)
= 80 - 7 
= 73 m
So, 
Area of the portion that covered by grass = 113*73
= 8249 sq m
