How do is calculate 40000 sq ft. 5000 sq ft. 10000 sq ft and 80000 sq ft into a 400 x 400 feet sq area?

Answer 1

It is not entirely clear what the question is asking but the areas can be configured as80000 sq ft = 400 * 200 sq ft leaving an area of 400 * 200 sq ft, then

40000 sq ft = 400 * 100 sq ft leaving an area of 400 * 100 sq ft, then

10000 sq ft = 100 * 100 sq ft leaving an area of 300 * 100 sq ft, then

5000 sq ft = 100 * 50 sq ft leaving an area of 250 * 100 sq ft.
