10cm by 10cm (perimeter=40cm),

5cm by 20cm (perimeter=50cm),

50cm by 2cm (perimeter=104cm),

100cm by 1cm (perimeter=202cm).

All of these rectangles' areas are 100cm2

What is the relationship for perimeter and area for rectangle?

There is no relationship between the perimeter and area of a rectangle. Knowing the perimeter, it's not possible to find the area. If you pick a number for the perimeter, there are an infinite number of rectangles with different areas that all have that perimeter. Knowing the area, it's not possible to find the perimeter. If you pick a number for the area, there are an infinite number of rectangles with different perimeters that all have that area.


If the area of the rectangle is 320cm squared find its perimeter?

Not enough data. Different rectangles (different length:width ratios) can have the same area, but different perimeters.


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.


How many different rectangles are there if the perimeter of the rectangle equals the area of the rectangle?

Infinite amounts.


What is the perimeter of a rectangle whose area is 21?

That depends on the rectangle! You can have different rectangles with the same area, but with different perimeters.


Why does rectangles have the same area and perimeter?

What is the perimeter in meters of a 28 acre field?

The perimeter for a certain area varies, depending on the figure. For example, a circle, different ellipses, a square, different rectangles, and different shapes of triangles, all have different perimeters or circumferences, for the same area.The perimeter for a certain area varies, depending on the figure.

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?

area = 144 square units perimeter = 48 units


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.


How many rectangles have the same area and perimeter of 18?

thare is only 1 differint rectangles


Can a rectangles perimeter be the same as the area?

Yes, it can because a 3 by 6 rectangle has the perimeter of 18 and has the area of 18! :)


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.


How do you calculate the perimeter and area of a shape?

Perimeter: add all sides area: multiply length times width for rectangles


How do you determine acreage from perimeter?

You would have to know what kind of figure you are talking about. For the same perimeter, you can have a different surface area, depending on whether you have a circle, a square, different kinds of rectangles, etc.


If a rectangles area is 12 cm squared what is the perimeter?

What is the perimeter of an area 36cm sqared?

The area doesn't tell you the dimensions or the perimeter. It doesn't even tell you the shape. -- Your area of 36 cm2 could be a circle with a diameter of 6.77 . (Perimeter = 21.27.) -- It could be a square with sides of 6 . (Perimeter = 24.) -- It could be rectangles that measure 1 by 36 (Perimeter = 74) 2 by 18 (Perimeter = 40) 3 by 12 (Perimeter = 30) 4 by 9 (Perimeter = 26). There are an infinite number of more rectangles that it could be, all with the same area but different perimeters.


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.


How much fence do you need for perimeter fence 8 acres?

The perimeter, for a given area, varies depending on the shape. It is different, for example, for a circle, for a square, and for rectangles of different length/width ratio.


What is the area of a square formed by six rectangles, given that the total perimeter of the six rectangles is 330 cm?

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.


What is the perimeter of a 6000 square meter block?

That depends on the exact form of the block - whether it is square, or different forms of rectangles. The perimeter to area ratio is not the same for all shapes.


What are some rectangles with the area the same as the perimeter?

A rectangle cannot really have the same area and perimeter because an area is a 2-dimensional concept while a perimeter is 1-dimensional.However, you can have rectangles such that the numericalvalue of their area and perimeter are the same.Take any number x > 2 and let y = 2x/(x-2)Then a rectangle with sides of x and y has an area and perimeter whose value is 2x2/(x-2)


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.
