Answer :
If the path runs diagonally, then a right angle triangle is made, with the width and length as the two sides, and the route taken as the hypotenuse.
Pythagorus' Theorem tells us that; A² = B² + C²
Where B and C are the two sides of a right angled triangle, and A is the hypotenuse.
Route taken = A
A² = B² + C²
A² = 3² + 6²
A² = 9 + 36
A² = 45
A = √45
A = 6.7 miles

as it will create a triangle with 90o angle the pythagory says 6+3²=x²⇔ x²=45⇔ x=√45
