Answer:
The area of the smallest section is 
The area of the largest section is 
The area of the remaining section is 
Step-by-step explanation:
Please see the picture below.
1. First we are going to name the side of the larger square as x.
As the third section shares a side with the larger square and the four sides of a square are equal, we have the following:
- Area of the first section:


- Area of the second section:
(Eq.1)
- Area of the third section:

(Eq.2)
2. The problem says that the total area of the enclosed field is 975 square yards, and looking at the picture below, we have:

Replacing values:

Solving for x:





3. Replacing the value of x in Eq.1 and Eq.2:
- From Eq.1:


- From Eq.2:
