A square a rectangle a pentagon a diamond or a triangle.
perimeter is when you have a shape and then you have your area and that is what is in the middle of the shape and perimeter is the edge of the shape.
Depends on the shape. If the space was 36x1, the perimeter would be 74. If the space was 18x2, the perimeter would be 40, and so on.
The question cannot be answered because it makes no sense. The perimeter - of a shape - is the outline of the shape. The is no unit in 20 outlines. Unless you count an outline as a unit and in that case, there are 20.
Perimeter is the outside of a shape
for a 4 sided shape... w+w+L+L=perimeter perimeter is the outside of a shape. add all of the sides to get the perimeter.
Perimeter is the outside. The area is the inside of a shape.
First of all, the area cannot be 40 cm since an area is 2-dimensional whereas the measure given is 1-dimensional. Next, the shape is not defined and so the width, length and perimeter are indeterminate. Even if you assume that the shape is a rectangle, the width, length and perimeter are indeterminate. On the basis that the length is greater than the width, all that you can say is that the length will be greater than or equal to sqrt(40) = 6.324555 (to 6 dp), the width will be 40 divided by that length and the perimeter will be twice their sum. Some examples: Length = 8, width = 5, perimeter = 26 Length = 10, width = 4, perimeter = 28 Length = 40, width = 1, perimeter = 82 Length = 4000, width = 0.01, perimeter = 8000.02 Length = 4,000,000, width = 0.00001, perimeter = 8,000,000.00002 and so on, without limit.
the perimeter or the circumference
The perimeter of a shape is the distance around the outside. For a shape with straight sides, the perimeter is the sum of the length of the sides. The perimeter of a circle is called the circumference, and is calculated by multiplying the diameter by pi.
The formula for the perimeter of a shape depends on the shape. It is the sum of the lengths of all the sides that enclose the shape.
It has a perimeter of 40.
If you want to enclose a certain area, the shape that does it with the shortest perimeter is a circle.
