Question

the Blackburn family has a square field where they keep their cattle the area of the field is 40000 ft squared and Mr Blackburn wants to put a fence diagonally through the field what should the length of the fence be

Answer 1

Answer: 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,

`\text{ Area of square}=Side* Side\\\\40000=Side^2\\\\√(40000)=Side\\\\200\ ft=Side`

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

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

`\text{ Diagonal of square}=√(2)Side\\\\\text{ Diagonal of square}=20√(2)\\\\So,\\\\\text{Length of fence along the diagonal}=20* 1.41=28.3\ ft`

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