area = length by length. 3 x 3 = 9 units squared
Add together the areas of all 6 sides.
The answer will depend on the nature of the polygon and what is known about it.For a triangle, for example, there are formulae if you know 3 sides; or 2 sides and an angle; or 1 side and 2 angles. In the second case you can find the area but not the perimeter.In the case of a quadrilateral, you will require much more information, and for polygons with more sides, even more.
first find the area of one face so 3times 3= 9 in. square then 9 in times all 6 sides =54 in. square
Divide the perimeter by 3 to find the length of each of its 3 equal sides Area = 0.5*side squared*sin(60 degrees) Alternatively use Pythagoras' theorem to find its height then area is: 0.5*base*height
area = length by length. 3 x 3 = 9 units squared
9 meters squared
Use trigonometry
Find the area of one of the sides and then multiply it by 3 (3 sides to a triangular pyramid)Then work out the area of the base of the pyramid, and add it to the total area of all the sides.Area of a triangle = Base x Height / 2

If those are sides of a quadrilateral, you can't calculate the area - there is insufficient information. The same sides can be connected at different angles, resulting in different areas.
There is no area because rectangles do not have equal sides.
You cannot. The length of the sides of a quadrilateral do not provide sufficient information to find its area. In the same way the a square can be distorted into a thinner and thinner rhombus with a smaller and smaller area, so can any quadrilateral.
Pythagoras' theorem is used to find any of the 3 sides of a right angle triangle if the 2 other sides are known.
