Can perimeter ever be more than area?

You can't really compare perimeter and area.

Perimeter is a linear measure, area is a two-dimensional measure. They are not directly comparable.

You get strange results if you do.

Lets say the radius of a circle is 3 cm.

The perimeter is 6pi cm

The area 9pi cm2

But 3 cm is exactly the same thing as .03 m.

So if we use .03 m instead, we get:

The perimeter is .06pi m.

The area is .0009 m2.

If we try to just compare the numbers without taking the units into account, we see that for exactly the same circle in the first case the area is a larger number, in the second case the are is a smaller number.

Can you calculate the area if you know the perimeter?

No, you can not calculate an area if you know just the perimeter. For example, rectangle with sides of 10 and 20 would have a perimeter of 60 and an area of 200, but a square of sides 15 would have a perimeter of 60 and an area of 225. You need to know more details about the shape than just the perimeter.


Is the perimeter of a polygon less than the area of the polygon?

if your perimeter totals the same as 4 times pi then the maximum area that can be encompassed is equal to the perimeter. This is done by forming a circle. if you change the shape of the circle then the area will become smaller than the perimeter(circumference) if you make the circumference of the circle smaller then you will definitely decrease the area faster than you would the perimeter if you make the perimeter bigger then you will definitely increase the area faster than you would the perimeter.


Is the area always larger than the perimeter?

No the area is not always larger than the perimeter. Ex. The area of a reectangle could be 4 feet. The width could be 4 while the length is 1. The perimeter total would be 10.


Can a rectangle have a greater perimeter and also have a greater area?

Of course, a rectangle can have a greater perimeter and a greater area. Simply double all the sides: the perimeter is doubled and the area is quadrupled - both bigger than they were.


Can perimeter be larger than area?

yes if you have a 1 by 1 rectangle, you would have a perimeter of 4 but an area of 1 [ADDED} It's really a meaningless question because although such numbers suggest that, you cannot compare a linear dimension (perimeter) with an area.

Is it sometimes always or never true that the perimeter of a rectangle is numerically greater than its area?

Sometimes. Experiment with a small square and with a large square (though any shape rectangle will do). A square of 4 x 4 has a perimeter of 16, and an area of 16. A smaller square has more perimeter than area. A larger square has more area than perimeter.


What is the area if the perimeter is 36?

The perimeter doesn't tell you the area. There are an infinite number of differentareas that it could have.-- If it's a circle with a perimeter of 36, then the area is 103.1324. (rounded)-- If it's a square with a perimeter of 36, then the area is 81 .-- If it's a rectangle with a perimeter of 36, then the area can be any numberthat's more than zero and less than 81 .

Is the perimeter larger than the area?

Yes it can but on some occasions the area can be more.


What is the perimeter for a polygon that's area is 20sq. units?

Even if you knew how many sides the polygon has, you stillcould not calculate its perimeter with that much information.Examples:-- An equilateral triangle with area of 20 has perimeter of 20.3885 .-- A square with area of 20 has perimeter of 17.889(rounded).-- A rectangle with area of 20 can have any perimeter more than 17.889 .4 by 5 . . . . area = 20, perimeter = 182 by 10 . . . area = 20, perimeter = 241 by 20 . . . area = 20, perimeter = 42..etc.

What is the least possible perimeter with an area of 169 ft?

The shape which minimises the perimeter for a fixed area is a circle. A circle of radius 7.334 ft (approx) will have the required area and a perimeter (circumference) of just 46.084 ft. The quadrilateral with the smallest perimeter will be a square with sides of 13 feet: a perimeter of 4*13 = 52 feet. Any regular polygon with more than 4 sides will have a smaller perimeter, for the same area, than a square.


Does a circle have more area space than other shapes?

Yes, for a fixed perimeter, a circle contains the largest area.


Can a shape have the same area but not perimeter?

Most shapes have different perimeter than area, as far as value.


Can a perimeter be larger than the area itself for example a 3x3 square with a perimeter of 12in and a area of 9in?

yes


Can area be smaller than the perimeter?

yes


What shape has a bigger area and a smaller perimeter?

Bigger than what ? Smaller than what ? If you have a certain perimeter and you want to cram the most area inside it, or if you have a certain area and you want to enclose it in the shortest perimeter, then you must make the perimeter circular. If you have only a limited number of fence posts and a circular perimeter isn't practical, then you make the perimeter square.
