To find the size of Field C, we need to find the area in acres.
Let's first count the number of squares inside Field A. From the given diagram, it seems like Field A consists of 9 squares. So, the area of Field A is 9 acres.
Next, let's count the number of squares inside Field B. From the diagram, it looks like Field B consists of 16 squares. So, the area of Field B is 16 acres.
To find the area of Field C, we need to use the Pythagorean Theorem. Let's say Field C is a square field.
Since Field C is formed by combining Field A and Field B, the area of Field C can be found by adding the areas of Field A and Field B.
Area of Field C = Area of Field A + Area of Field B
Area of Field C = 9 acres + 16 acres
Area of Field C = 25 acres
So, the area of Field C is 25 acres.
