Answer:
The area of the cornfield is 1,529 yards.
Explanation:
In this case, since the statement indicates that it is a square field, you have to use the formula to calculate the area of a square, which is:
A=a², where:
A is the area
a is the lenght of side
The statement says that one side measures 39 yards, so this would be a, and you can replace this value on the formula:
A=39²
A=1,521
According to this, the answer is that the area of the cornfield is 1,529 yards.
