=
16Each side is 16 meters. I hope this helps!
Answer:
Second option: 
Third option: 
Fifth option: 
Step-by-step explanation:
By definition, a perfect square trinomial can be obtained by squaring binomials.
Then:
Knowing this, to obtain a perfect square trinomial, the binomials that you multiply must be equals.
Therefore, the products result in a perfect square trinomial are:
Want it exact? Here it is:499.243083(got it from my calculator), if rounded, then here it is:500
Answer
Subtract 
from 
then;
Remove the bracket we have;
Like terms are those terms which have same variable to the same power.
Combine like terms;
Therefore, Subtracting from we get
area = pi times radius squared
area = pi times 5 squared
area = pi times 25
area = 78.54
answer : 78.54 square feet
