Excel Page Width Error

[cakarem]

Hi,
I'm often using Excel. But , i can not understand issue that:
I set page size to A4 ( 210 x 297 mm ) . Then i add rectangular which width size is 210 mm to my sheet. Despite rectangular width and page width is same, rectangular is not fit on the page and is overflow on the page.
How can i fix this problem?
Note: Page margins is zero.

Example Page:

@jitinm You dont understand me. Can you try that you should add shapes ( exp. rectangular shape)

[#5]

@cakaremsee this one then. 8.27 is the width size of A4 sheet

@jitinm  i examined to your file. But i see that your use scaleing. Please not use scale. Original size %100 scale

@cakarem If you see even after setting the margins to "0" there is still gap left in left and right which cannot be removed and it will stay. So considering that in mind you need to adjust one or the other thing. I hope you understand.

Perfect, you start understanding me. So, i how learn size of stiil gap left or right. Why is there gap there.
I just it must be fit and must not be overflow when i want to add rectangular which width size 210mm on page which size is A4 size ( there shouldn't be not left or right gap. How its zero )
OR
how should i place it on page ( margin is zero or equals gap )
