There are many possible answers. You could draw a 4 cm x 7 cm rectangle and remove a 1 cm x 3 cm rectangle from it.
width 1, length 10 width 2, length 5
Two dimensions (2D) is a shape that has a length and width. For instance, draw a square on a piece of paper and it is in 2D.
To draw a shape with the same area and perimeter, decide what shape you want to draw, then take the equations for area and perimeter and make them equal, and then solve what the various side lengths have to be. For instance, the area of a square is L2 where L is the side length, and the perimeter of a square is Lx4 We want them equal, so L2=Lx4 Dividing both sides by L gives us L=4, so if I draw a square with side length 4, it will have the same area and perimeter.
It is easier to understand if you draw on graph paper. Each little square represents one unit of area. So if you have a square with 4 little squares in it, then the length is 2 and the width is 2. Multiplied together it makes 4. A similar idea happens when you don't have a shape on graph paper. Instead, you use the info you are told, even if you are given a picture that doesn't look that size.
That's going to depend on the shape of the shape.

The rectangle would have a width of 2 and a length of 4.

For rectangular pools, multiply the length times the width. For other regular shapes use formulas for the appropriate geometry. For irregular shapes, the simplest way is to draw the shape on paper and use a planimeter to determine the area. If you are clever, you can use a tracing of the shape and a good balance to determine the surface area.
Area= width x length Alternatively, area of irregular or regular polygons can be calculated using SketchAndCalc (see related links below). A free Area and Perimeter Calculator that calculates the area of any shape you draw, regardless of scale or complexity.

No. If you draw a rectangle there are four sides, the length of two of those sides are equal to the length, and the other two are equal to the width. Therefore: the perimeter, which is equal to all the sides added up, is equal to two times the length plus two times the width: or 2L+2W= Perimeter. If you know L and you know the perimeter you can solve it algebraically. the width equals the perimeter minus two times the length, all that divided by two, or W= (P-2L)/2 (when you do the algebra). you might be thinking about the area in which case if you knew the area and the length and you want to find the width you would divide the area by the length.

Draw the table and calculate the area of the triangle the area of a square is 36
by drawing a circle but a little longer in length
They can be: 1 by 81, 3 by 27 and 9 by 9 as integers in cm
