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.
2D shapes are flat and have only two dimensions—length and width—while 3D shapes include depth, adding a third dimension. This allows 3D shapes to occupy physical space, whereas 2D shapes are confined to a plane. Additionally, 3D shapes can have volume and surface area, whereas 2D shapes are characterized by perimeter and area. Examples include squares and circles for 2D shapes, and cubes and spheres for 3D shapes.
base is for 2d shapes and area of base is for 3d shapes
what are the 2d shapes of the real world
A 2D shape can be measured in two dimensions: length and width. These dimensions define the shape's area, which is the space it occupies on a flat surface. Unlike 3D shapes, 2D shapes do not have depth, so height is not considered in their measurement. Examples of 2D shapes include squares, circles, and triangles.
the cylinder has 2 2d shapes: the 2 circles on the end

base is for 2d shapes and area of base is for 3d shapes
That will depend on what they are but in general 3D shapes have surface area and volume whereas 2D shapes have only surface area.
2d shapes are shapes that can only be seen from the front unlike 3d shapes and they are flat

u times the length by the width. ( that means times the line going across buy the line going down)
