Yes, I could draw three rectangles with 12 units, so long as the perimeter of the rectangles sum up to 12.
You're probably asking for integer lengths, though. A square is a special type of rectangle where all the sides are the same length, so I could have 3 squares with a side length of 1 unit, which gives 3x(1x4)=12 units.
Thee different rectangles with an area of 12 square units are 3 by 4, 2 by 6 and 1 by 12.
1 x 5 2 x 4 3 x 3
There are three possibilities.. 1 x 12... 2 x 6 & 3 x 4

If you restrict yourself to whole numbers, 12 has 3 factor pairs: 1 x 12 2 x 6 3 x 4
3.1 and 2.9 units 3.2 and 2.8 units 3.3 and 2.7 units etc or 3.01 and 2.99 units 3.02 and 2.98 units 3.03 and 2.97 units etc. All you need to do is to have two different postitve numbers that sum to 6 (half of 12)
1 x 5 2 x 4 3 x 3
Assuming the 12 squares are the same size, three. And three more if you count different orientations (swapping length and breadth) as different rectangles.
yes
You can make three rectangles. Remember that a square can also be a rectangle.5x14x23x3
