Answer:
The fencing needed is 20 feet.
Step-by-step explanation:
The area of the rabbit cage is 25 sq ft.
Becky is building a square rabbit cage.
As the cage is square, so all its side will be same. Area of square is [tex](side^{2})[/tex]
The side of the cage will be = [tex]\sqrt{25} =5[/tex] feet
So, the fencing (perimeter) needed is = [tex]4\times5=20[/tex] feet
