Answer: Option B

Explanation:

The scale of the map is 1 cm to 100 m. This means that 1 cm on the map represents 100 meters in reality.

Given that the length on the map is 3.25 cm, you can find the actual length by multiplying it by the scale factor:

Actual length = Length on map × Scale factor = 3.25 cm × 100 m/cm = 325 m

Now, you mentioned that the area of the rectangular field is 52000 square meters. The area of a rectangle is given by the formula:

Area=Length×Breadth

We know the area is 52000 square meters and the length is 325 meters. Substituting these values into the formula, we can find the breadth:

52000m2=325m×Breadth

Breadth=325m52000m2

Breadth=160m
