What is the area of two rectangles that have different perimeter which is 12 and 18?

The perimeter of a rectangle gives only a maximum for the area, there is no minimum because the rectangle can be an infinitesimally thin but long rectangle with an area as small as you like.
The maximum area is attained when the rectangle is, in fact, a square.
So perimeter 12 => max area = 3*3 = 9 square units.
and perimeter 18 => max area = 4.5*4.5 = 20.25 sq units.
So the two can have the same area for any value in the range (0, 9].
You say 2?
Smaller rectangle = 0.3542 * 5.6458
and the larger = 0.2300 * 8.7720
If you want an area of S square units
then
smaller rectangle = 0.5*[6-sqrt(36-2*S)] by 0.5*[6+sqrt(36-2*S)]
and
larger rectangle = 0.5*[9-sqrt(81-2*S)] by 0.5*[9+sqrt(81-2*S)]

What is the area and perimeter of a large square if two congruent rectangles are arranged so they from a square with each perimeter of rectangles is 36 inches?
area = 144 square units perimeter = 48 units
Is the area the same on all rectangles with the same perimeter?
No, it is not. I'll give you two examples of a rectangle with a perimeter of 1. The first rectangle has dimensions of 1/4x1/4. The area is 1/16. The second rectangle has dimensions of 3/8x1/8. The area is 3/64. You can clearly see that these two rectangles have the same perimeter, yet the area is different.
Would Two rectangles that have a same perimeter are congruent?
No
Are all rectangles with the perimiter of 20 feet equal the same area?
No. For example, a 1 ft by 9 ft rectangle (2 sides of length 1 and 2 sides of length 9) has perimeter 20 ft and an area of 9 square feet. But a 4 ft by 6 ft rectangle also has a perimeter of 20 feet, but an area of 24 square feet. These two rectangles both have the same perimeter of 20 feet but different areas.
Do these rectangles have the same perimeter- 12 m x 4 meters and 13 m x 3 meters?
Yes The first has 2 sides of 4 and two of 12 -- so the perimeter is 32 meters with an area of 48 Sq meters. The second has two sides of 3 and two of 13 ----- so the perimeter is 32 meters with an area of 39 Sq meters. (the areas a different).
Do two different rectangles with the same perimeter necessarily have the same area?
no
How do you convert perimeter into square meters?
There is no standard relationship between perimeter and area. For example, you can have two rectangles that have the same perimeter, but different area.
Can different rectangles have the same area and perimeter?
It's very easy for two rectangles to have the same area and different perimeters,or the same perimeter and different areas. In either case, it would be obvious toyou when you see them that there's something different about them, and theywould not fit one on top of the other.But if two rectangles have the same area and the same perimeter, then to look at themyou'd swear that they're the same rectangle, and one could be laid down on the otherand fit exactly.
Draw 2 rectangles with same perimeter but difference area?
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.
What is the area and perimeter of a large square if two congruent rectangles are arranged so they from a square with each perimeter of rectangles is 36 inches?

No, it is not. I'll give you two examples of a rectangle with a perimeter of 1. The first rectangle has dimensions of 1/4x1/4. The area is 1/16. The second rectangle has dimensions of 3/8x1/8. The area is 3/64. You can clearly see that these two rectangles have the same perimeter, yet the area is different.
Can rectangles with the same perimeter have different areas?
Yes. Say there are two rectangles, both with perimeter of 20. One of the rectangles is a 2 by 8 rectangle. The area of this rectangle is 2 x 8 which is 16. The other rectangle is a 4 by 6 rectangle. It has an area of 4 x 6 which is 24.
If two rectangles have the same area do they also have to have the same perimeter?
Not necessarily. Let's say that there is a circle with the area of 10. Now there is a star with the area of 10. They do not have the same perimeter, do they? That still applies with rectangles. There might be a very long skinny rectangle and a square next to each other with the same area, but that does not mean that they have the same perimeter. Now if the rectangles are congruent then yes.
Is it true that the greater the perimeter the greater the area?
No, in general that is not true. For two similar figures it is true. But you can easily design two different figures that have the same perimeters and different areas, or the same area and different perimeters. For example, two rectangles with a different length-to-width ratio.
Can two rectangles have a different shape but have the same perimeter?
Yes. A 1 x 4 and a 2 x 3 have the same perimeter.
How do you work out area in cm2 from perimeter?
If the sides are in cm, then you would multiply the length of the shape by the width, which equals area. And area is in the unit of the sides but squared. So in this example it would be cm2. ========================================= The answer to the question is: You can't. The perimeter doesn't tell you what the area is. You can have two different drawings with the same perimeter and different areas, or with the same area and different perimeters. Even if they're both triangles, or both rectangles, etc. You can't take perimeter and 'work out' area from it.
Would Two rectangles that have a same perimeter are congruent?
No
