To calculate the remaining number of teams, use the sequence formula:
a(n) = a(1)Rⁿ-¹
Where a(n) and a(1) are the nth and first terms. R is the factor. Therefore, 24 teams is valid value.
After 5 rounds :
a(5) = 128*(½)⁴
a(5) = 128/16 = 8
8 teams are remained.
It is given in the question that
A farmer owns about 960 acres of land. If his farm is square.
First we convert acres to miles square, and the conversion expression is

Therefore,

Let the side length of the square be x miles .
And the formula of area of square is

1 is for circle
2 is for triangle
3 is for surface area
4 is for volume
This is very sloppy but u hope it helps
