Re: divide a rectangle in two block
Hi;
Maximum percentage of what?
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Re: divide a rectangle in two block
Hi tina123;
I have the same question. Percentage of what? Area? Points?

Re: divide a rectangle in two block
Hi;
How do you want to split the big rectangle up? With one line or more than one line. Please look at the drawings.

Re: divide a rectangle in two block
For the 8 x 16 rectangle you have in the picture. This is one answer.

hy .. bottom block is small .
second block should be 1st block.
I want 30% area should be for 1st block and the rest 70% area should be for 2nd block .
you did opposite .
and please let be know how did u do that .

Hi;
You want the top block to be the small one?

Re: divide a rectangle in two block
Hi;
30% of ( 8 * 16 ) is 38.4. You need a rectanghle with an area of 38.4.
The width is 8 so we can only adjust the length from 0 to 16. We solve that with algebra.
L = 4.8
So the dimensions of the rectangle are 4.8 x 8. See the drawing.
