# What is the area and perimeter for 144cm X 162cm?

###### Wiki User

###### May 07, 2008 6:21AM

The perimeter (measured in cm) is the length around so you would just add 144 + 162 + 144 + 162. The area (measured in sq. cm) is how much the surface covers. It is just multiplying 144 x 162.

### If two shapes have the same perimeter will they have the same area?

Not at all. For example:
A square of 2 x 2 will have a perimeter of 8, and an area of 4.
A rectangle of 3 x 1 will also have a perimeter of 8, and an
area of 3.
A "rectangle" of 4 x 0 will also have a perimeter of 8, but the
area has shrunk down to zero.
The circle has the largest area for a given
perimeter/circumference.

### What is the largest area that you can have if the perimeter is 24 feet?

You get the largest area with a circle. Divide the perimeter by
(2 x pi), then calculate the area with the formula pi x
radius2.

### If The area of a rectangle is 176 sq cm what is the perimeter?

You can't tell the perimeter from knowing the area.
There are an infinite number of rectangles with different
dimensions that all have the same area.
Here are a few examples.
1 x 176 . . . perimeter = 354
2 x 88 . . . perimeter = 180
4 x 44 . . . perimeter = 96
8 x 22 . . . perimeter = 60
16 x 11 . . . perimeter = 54
13.266 x 13.266 . . . perimeter = 53.066
All of these have an area of 176, but they all have
different perimeters.
The last one on the list is a square. That's the rectangle with
the shortest possible perimeter
that has the area you want.
The perimeter of this square is 53.066. You can make a rectangle
with any perimeter
more than that, and an area of 176.

### How do you find the area and perimeter with no numbers just letters?

enter-net
______________
It depends on the shape of the area you are referring to.
1) For a square with side "a", the area is (a squared) and the
perimeter is 4 x a
2) For a rectangle with sides "a" and "b", the area is a x b and
the perimeter is
2 x (a + b)
3) For a circle with radius "a", the area is pi x (a squared)
and the perimeter (for a circle it is the circumference) is 2 x pi

### What is the area of a perimeter of 20 centimeters?

The perimeter and area don't depend on each other. Knowing
one
doesn't tell you the other.
-- A circle with perimeter (circumference) of 20 cm has area of
31.83 cm2.
-- A square with perimeter of 20 cm has area of 25 cm2 .
-- A (9 x 1) rectangle has perimeter of 20 cm and area of 9 cm2

### 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 numerical
value 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 find the area of a rectangl if you only have the perimeter?

With great difficultly.
The area could be any value greater than 0 units2 and less than
or equal to the area of a square with the given perimeter which
would be 1/16 x perimeter2 units2.
To know which of the possible areas you would need to know the
length of one side, then you can work out the area:
perimeter = 2 x (length + width)
⇒ width = (1/2 x perimeter) - length
⇒ area = length x width
= length x ((1/2 x perimeter) - length)
= (1/2 x perimeter x length) - length2

### What is the perimeter of the rectangle which is 32 square inches?

You can't tell. The area doesn't tell the dimensions or
perimeter.
If the rectangle's area is 32 square inches, here are ten

ALL of these have 32 square inches of area, and there are
many, many more:
0.8 x 40 . . . . . . Perimeter = 81.6 inches

there is no largest possible perimeter.
You can make it as large as you want, with no limit.

###### Asked in Math and Arithmetic, Algebra, Geometry

### What is the formula for area and perimeter?

Area is the total space within a shape or region. Perimeter is
the length along the outside edge (circumference for a closed
curve).
Different shapes have different formulas.
Examples:
For a square:
Area = (side)2
Perimeter = 4 x (side)
For a circle:
Area = (pi)x (radius)2
Perimeter = (2 pi) x (radius)
For a rectangle:
Area = (length) x (width)
Perimeter = (2 x length) + (2 x width)
As you can see, you really have to know which shape you're
talking about,
and then pick the right formulas for it.

### How can a figure have the same area and a larger perimeter?

Consider a square with sides of length x cm whose area is x2 cm
and perimeter is 4x cm.
Next consider a rectangle with sides of 2x cm and x/2 cm. It
area is 2x*x/2 = x2, the same as for the square. But its perimeter
is 2*(2x+x/2) = 5x > perimeter of the square.
Perimeter of 3x * x/3 = 62/3x cm.
Perimeter of 100x * x/100 = 200.02x cm
Perimeter of 1000000x * x/1000000 = 2000000.000002x cm.
As you can see, it is possible to increase the perimeter without
limit.
