Hi tina123;

I have the same question. Percentage of what? Area? Points?

Hi;

How do you want to split the big rectangle up? With one line or more than one line. Please look at the drawings.

For the 8 x 16 rectangle you have in the picture. This is one answer.

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.
