You times the length by width, to get the area of the 2D shape.
Area of a rectangle is length times width.
It depends on the shape of the area you are trying to find. The most basic calculation would be the area of a rectangle, which is A = lw (area = length times width).
You would find the area of the inside and outside shape (pretending that the inside shape was not in the outside shape). then, you would take the area of the outside shape and subtract the area of the inside shape.
Shape of what ?
The perimeter has nothing to do with the area you have to times the width times height times length and that will give you the area of the shape

you times it
length times width
you times the width by the legnth of the shape and then add them together

To find the length of a triangle or what ever shape your trying to find all you have to do is multiply width times the area. * * * * * Or, if you want the correct answer, you could try to divide the area by the width. That assumes the shape is a rectangle and that the area and width are known!
I cannot answer this question because I don't know what the shape in question is.
You would find the area of the inside and outside shape (pretending that the inside shape was not in the outside shape). then, you would take the area of the outside shape and subtract the area of the inside shape.
It depends on what type of shape you are trying to find the area. If it is a rectangle, you do base times height. For triangles, you do base times height divided by two. For a circle, it is Pi*R^2.
