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
