The blackburn family has a square field where they keep their cattle. the area of the field is 40,000ft squared, and mr blackburn wants to put a fence diagonally through the field. what should the length of the fence be?

Area of a square =a^2 
40000=a^2
a=200 inch

Now if u can imagine a square shape with side of 200 inch each.it makes right angles 
so use pythagorean theorm 

c^2=a^2+b^2
c^2=(200)^2+(200)^2
c=282.84 inch

ength of a fence is 282.84 inch
