There are different methods to work out the exact areas for different shapes. These work for regular shapes or ones that can be built up from regular shapes (such as a rectangle with a semicircle sitting on top). It is usually not possible to work out the exact area of an irregular shape but should be possible to estimate areas of any 2-d shape. One method is given below: Mark the shape out on a grid (a sheet of paper with squares marked out on it). Count all squares where more than half the square is inside your 2-d shape = X. Count the number of squares where (about) half is inside your shape = Y. Ignore all squares where less than half is inside your shape. Then X + Y/2 will be a good estimate of the area of your shape. The smaller the squares in the grid, the more accurate the estimate but also, the greater the number of squares that will have to be counted.

What is the Difference between base and area of base?
base is for 2d shapes and area of base is for 3d shapes
Is there any 2d shapes in the world?
what are the 2d shapes of the real world
How many 2d shapes does a cylinder have?
the cylinder has 2 2d shapes: the 2 circles on the end
How do you tell if a shape is 2d or 3d?
Polygons are 2d shapes whereas polyhedrons are 3d shapes
Is volume only for 3D shapes?
The volume of anything is always the area of the base of the object times the height. Therefore, to find the volume the object must have a height, which makes volume work with all 3D shapes. If one is looking at a 2D shape, then there is no height so a volume cannot be calculated (note: areas may be found of 2D shapes).
What is the Difference between base and area of base?
base is for 2d shapes and area of base is for 3d shapes
Which is a 3d shape?
That will depend on what they are but in general 3D shapes have surface area and volume whereas 2D shapes have only surface area.
What are 2d-shapes?
2d shapes are shapes that can only be seen from the front unlike 3d shapes and they are flat
What are 2D shapes?
2d shapes are shapes that can only be seen from the front unlike 3d shapes and they are flat
All 2d shapes with pictures?
it is all the 2d shapes with pics
Is there any 2d shapes in the world?
what are the 2d shapes of the real world
How do you work out the area of 2D shapes?
u times the length by the width. ( that means times the line going across buy the line going down)
Dimensions of 2D shapes?
The 2 dimensions of 2d shapes and length and breadth.
What 2d shape?
2d shapes are shapes that can only be seen from the front unlike 3d shapes and they are flat
How do the 2D shapes that make a rectangular prism help solve for the volume?
The answer depends on what is known about the 2d shapes.The answer depends on what is known about the 2d shapes.The answer depends on what is known about the 2d shapes.The answer depends on what is known about the 2d shapes.
How is 2d related with 3d?
Not too sure of the question but 2 dimensional shapes have only surface area whereas 3 dimensional shapes have surface area and volume
What are all of the 2d shapes?
There are infinitely many 2d shapes so it is impossible to list them all.
