If given the total perimeter only it is impossible to do.

However, if the lengths of each part of the perimeter are given (or can be worked out from the lengths given) then split the shape's area up into areas of shapes whose area you do know how to calculate, calculate each area and add them up.

For example if you have a hexagonal L shape with lengths 1cm, 3cm, 3cm, 1cm, 4cm, 4cm, (all angles 90o) it can be split into two rectangular areas, one of 1cm x 3cm (from the top of the back of the L to the top of the piece across the bottom) and the other of 4cm x 1cm (all the way across the bottom of the L).

How do you find the perimeter of a hexagon if the area is given?

In general you cannot find the perimeter of any shape if only the area is given.


How do you find Length and width whe area and perimeter are given?

It depends on the shape.


What is the perimeter of 8276.4 square feet?

There is not a single perimeter associated to a given area. You can have different perimeters, depending on the shape.


How do you determine area if perimeter is given?

More information is required in order to answer this question. What is the shape for which the perimeter is given? If it anything other than a circle or regular polygon it is not possible to determine the area. For a circle or regular polygon, the answer will depend on the shape.


If the area is 350square feet what is the perimeter?

There is insufficient information to answer the question. For a given area, the perimeter depends upon the shape. For a given area, the circle will have the smallest perimeter. For polygons, regular polygons will have a smaller perimeter than an irregular one of the same area. Also, for regular polygons, the greater the number of sides, the smaller the perimeter.


What shapes have the same perimeter but different areas?

Most shapes can have the same area and different perimeters. For example the right size square and circle will have the same are but they will have different perimeters. You can draw an infinite number of triangles with the same area but different perimeters. This is before we think about all the other shapes out there.


What is a perimieter?

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.

How to draw a shape with a perimeter that is 12 or 15 or 18 or 21 and the area is 12?

The perimeter and area of a shape do not provide sufficient information. With a given perimeter, the largest area that you can enclose is a circle, but you can then flatten the circle to reduce its area. Similarly, in terms a of quadrilaterals, a square has the largest area, but it can be flexed into a rhombus whose area can be made as small as you like. All that can be said is that there is no shape with a perimeter of 12 units whose area is 12 square units.


How do you find the perimeter using area?

Depending on the figure given you can find the area from the perimeter For example- If you have a square with a perimeter of 24, you divide 24 by 4 because all the sides of a square are congruent. In turn you will 6 as each side of the square The formula for the area of a square is side2 so you get 62 which is 36. The area is 36


Is perimeter and area the same?

No , perimeter is the measurement outside of the shape; the border. Area is the measurement of inside of the shape.


What is the shape for a figure to have a perimeter of 20 and an area of 18?

Perimeter and area are not sufficient to determine the shape of a figure.
