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

Length of fence along the diagonal is 28.3 feet.

Step-by-step explanation:

Since we have given that

The Blackburn family has a square field ,

Area of square = 40000 ft square

As we know the formula,

Area of square = Side x Side

40000 = slide

20 ft = Side

But Blackburn wants to put a fence diagonally through the field ,

As we know the formula for "Diagonal of side" i.e.

Diagonal of square

Diagonal of square 20

So,

Length of fence along the diagonal = 20 x 1.41 = 28.3

Hence, length of fence along the diagonal is 28.3 feet.

Hope this helps!

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

x = 3 ± √(5+y)
