Answer 1

Hint: In pictographs we first see what is the value of one picture? After knowing it, we can easily find the value of different components given in the pictograph.

Complete step-by-step answer:
We know that pictographs are another way of representing data. In which data is given in the form of pictures. That is why this form of representing a date is named as pictograph.
In pictograph data is represented in the form of a picture. Where each picture represents a fixed value and is always defined in the pictograph.
Here, in this given pictograph each ball represents the area of the district.
If there are two balls then value will become two times $ 1000\,\,sqkm $ .
For example in the above pictograph we see that for Koria there are six complete balls.
Hence, its value will be six times the value of one ball.
As, value of one ball is $ 1000\,\,sqkm $ mentioned in the pictograph.
Hence, area of Koria will be given as: $ 6 \times \left( {1000} \right) $
  $ \therefore $ Area of Koria = $ 6000\,sqm $
Hence, from above we see that area of Koria district is. $ 6000\,sqm $

Note: While doing calculations in pictograph problems, one must understand pictograph carefully and see what is exact value of one picture given in pictograph and if the picture is not completed or half then its value will be considered as half and so as of the given picture.
