Thee different rectangles with an area of 12 square units are 3 by 4, 2 by 6 and 1 by 12.
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.
There are three possibilities.. 1 x 12... 2 x 6 & 3 x 4
1 unit x 5 units2 units x 4 units3 units x 3 units
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
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.
You can make three rectangles. Remember that a square can also be a rectangle.5x14x23x3
There are an infinite number of rectangles with this perimeter. The "whole number" sides could be (5 x 1), (4 x 2) or (3 x 3), but (5½ x ½) or (3¼ x 2¾) etc would fit the description.
No, rectangles with the same area do not necessarily have the same perimeter. The perimeter of a rectangle depends on both its length and width, while the area is simply the product of these two dimensions. For instance, a rectangle measuring 2 units by 6 units has an area of 12 square units and a perimeter of 16 units, while a rectangle measuring 3 units by 4 units also has an area of 12 square units but a perimeter of 14 units. Thus, different length and width combinations can yield the same area but different perimeters.
3 or 6, depending on whether rectangles rotated through 90 degrees are counted as different. The rectangles are 1x12, 2x6 3x4 and their rotated versions: 4x3, 6x2 and 12x1.
