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 net for a rectangular prism, start by unfolding the prism into its six rectangular faces. Typically, this consists of two rectangles for the top and bottom and four rectangles for the sides, arranged in a way that they can be folded back into the prism shape. To find the surface area, calculate the area of each rectangle (length × width for the top and bottom, and width × height or length × height for the side rectangles) and then sum all the areas together. The formula for the surface area of a rectangular prism is (2lw + 2lh + 2wh), where (l), (w), and (h) are the length, width, and height, respectively.
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.
To draw a rectangle with an area of 36 cm² and a perimeter of 40 cm, you first need to determine the dimensions. The area ( A ) is given by ( A = length \times width ), so ( lw = 36 ). The perimeter ( P ) is given by ( P = 2(length + width) ), so ( 2(l + w) = 40 ), which simplifies to ( l + w = 20 ). Solving these equations, you find that the dimensions are 18 cm (length) and 2 cm (width) or vice versa. You can then use these measurements to draw the rectangle.

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

Well, isn't that a happy little challenge! To draw a shape where the perimeter is twice the area, you can start with a rectangle. Let's say the length is 4 units and the width is 1 unit. The perimeter would be 10 units (4+4+1+1) and the area would be 4 square units (4x1). Keep painting those shapes and exploring the joy of numbers!

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.
To create a shape with an area of 16 square centimeters and a perimeter of 20 centimeters, you can use a rectangle. For example, if you choose a length of 8 centimeters, the width would need to be 2 centimeters (since area = length × width = 8 cm × 2 cm = 16 cm²). The perimeter can be calculated as 2(length + width) = 2(8 cm + 2 cm) = 20 cm. Thus, a rectangle measuring 8 cm by 2 cm meets both criteria.
To draw a rectangle with an area of 35 square units and a perimeter of 35 units, you can use the formulas for area (A = length × width) and perimeter (P = 2(length + width)). Let the length be ( l ) and width be ( w ). From the area, you get ( lw = 35 ), and from the perimeter, ( 2(l + w) = 35 ) or ( l + w = 17.5 ). Solving these equations simultaneously, you can find suitable dimensions, such as ( l = 10 ) units and ( w = 3.5 ) units or ( l = 7 ) units and ( w = 5 ) units.
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.
