Solution

The correct option is B Length = 47 km ; Breadth = 25 kmCase 1: Total parts=35 Total area=1×1=1 sq. unit Area of one section=135 sq. units Area of overlapping sections=135×16 =1635 sq. unit ⟹Area of the park=1635 sq. km Case 2: Total parts=35 Total area=1×1=1 sq. unit Area of one section=135 sq. units Area of overlapping sections=135×8 =835 sq. unit ⟹Area of the park=835 sq. km Case 3: Total parts=35 Total area=1×1=1 sq. unit Area of one section=135 sq. units Area of overlapping sections=135×4 =435 sq. unit ⟹Area of the park=435 sq. km Case 4: Total parts=35 Total area=1×1=1 sq. unit Area of one section=135 sq. units Area of overlapping sections=135×12 =1235 sq. unit ⟹Area of the park=1235 sq. km So, the only case where the total area is 835 sq. km is in case 2. ∴The dimensions of the park could be: Length = 47 km ; Breadth = 25 km
