Answer:
B. 19 feet
Step-by-step explanation:
Given area of enlarged field =[tex]576 feet^2[/tex]
Let the length of the field be x.
Since the field is in square shape so breath is equal to the length that is also x.
∴ Side of the enlarged field = [tex](x+5)[/tex]
We all know that area of square = [tex]length\times breath[/tex]
Now substituting the values we get;
[tex](x+5)\times(x+5)=576\\(x+5)^2=576\\(x+5)^2=24^2\\x+5=24\\x=24-5=19[/tex]
Hence the side length of the original field was 19 feet.
