Question 1
:
a) 3 by 3 square has an area of 9 square feet
b) say there are E people on a 3 by 3 square
c) 100 by 150 field has an area of 15000 square feet
:
there are (1500 / 9) squares of 3 feet by 3 feet = 1666.666666667 approx 1666.7 squares
:
**********************************************************************
we estimate that there are (1666 * E) + (0.70 * E) people on the field

Question 2
:
a) 10 by 10 square has an area of 100 square feet
b) say there are E people on a 10 by 10 square
c) 250 by 250 field has an area of 62500 square feet
:
there are (62500 / 100) squares of 10 feet by 10 feet = 625 squares
:
********************************************************
we estimate that there are (625 * E) people on the field
