There are infinitely many rectangles. Let K = sqrt(11). Let L be any real number greater than M and let B = 11/L. Then, B < K so that for any two different values of L, the pair (L, B) are distinct even with a swap.
The rectangle with length L and breadth B has an area = L*(11/L) = 11 cm2. Since there are infinitely many choices for L, there are infinitely many rectangles.
This browser is hopeless for drawing but consider the following two rectangles: a*b and (a+1)*(b-1). Their perimeter will be 2a+2b but unless a = b-1, their area will be different.
A centimetre squared is a measure of area; it can have any shape. The easiest area of 1 centimetre squared (to draw/visualise) is a square with one centimetre on each side.
If you restrict yourself to whole numbers, 12 has 3 factor pairs: 1 x 12 2 x 6 3 x 4
If the room is rectangular, multiply the the lengths of the walls. If the shape is not rectangular, you will need to break it up into rectangles or squares. Draw it out on paper and break it up into smaller parts whose area you can find.
Draw a square and divide it into six equal rectangles, for example: ................................... ... ------------------ ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... ------------------ ... ...................................

Squares are rectangles. Draw a 2 unit square.
To find the different rectangles with an area of 28, we need to determine the pairs of factors of 28. The factor pairs are (1, 28), (2, 14), (4, 7), and (7, 4), which represent the dimensions of the rectangles. Since the order of length and width doesn't matter, we have four unique rectangles: 1x28, 2x14, 4x7, and 7x4. Therefore, there are three distinct rectangles based on unique dimensions: (1, 28), (2, 14), and (4, 7).

Its pretty much 11 rectangles in one.
The area of a circle is: pi times radius squared
They can be: 1 by 81, 3 by 27 and 9 by 9 as integers in cm
Rectangles don't have volume, they have area. Only 3 dimensional figures have volume.
Just draw a square. Squares are rectangles.
If you restrict yourself to whole numbers, 12 has 3 factor pairs: 1 x 12 2 x 6 3 x 4
it is 3 squared
