Mind-Bending Puzzle That Will Challenge Your Intellect

#brainteasers :
A carpenter had a rectangular wooden board.
He wanted to have a circular hole exactly at the center, but he was drunk, so he drilled the hole inaccurately, off the mark.
Now he needs your help to fix this mistake, by using a hacksaw.
So, the objective is to cut the board into pieces and reassemble them to form a rectangle of the same dimensions as the original, but with the circular hole in the exact center.
You should follow certain rules:
1 - You can only perform straight cuts.
2 - You are not proficient in using a handsaw, so, you can only start cutting from the outer edges of the board.
The challenge is to achieve this task with a minimum number of straight cuts.

Puzzle:
What is the minimum number of straight cuts required to successfully accomplish the task?
This puzzle is known as Umbrella stand puzzle (aka, dissection puzzle).
