# maths perimeter and area formulas working model

In this post we write about making of the maths perimeter and area formulas working model – maths tlm – diy | craftpiller

Creating a working model to represent the perimeter and area formulas for polygons using cardboard and color paper can be an excellent way to visualize and understand these concepts.

Let’s build a simple model that represents different polygons and showcases their perimeter and area formulas.

Materials needed:

1. Cardboard (for the base and structures)
2. Color paper (for representing different polygons and formulas)
3. Scissors
4. Glue or double-sided tape
5. Marker pens or sketch pens

Polygons to include in the model:

1. Square
2. Rectangle
3. Triangle
4. Circle
5. Parallelogram

Step-by-step instructions:

1. Base:
• Cut a large rectangular or square piece of cardboard to serve as the base for the model.
2. Shapes Representation:
• Use color paper to create representations of each polygon (square, rectangle, triangle, circle, parallelogram).
• Cut out shapes from color paper based on their respective dimensions.
3. Perimeter and Area Formulas:
• Write the formulas for perimeter and area on separate small rectangles of color paper for each polygon.
• For example:
• Square: Perimeter = 4 × side, Area = side × side
• Rectangle: Perimeter = 2 × (length + width), Area = length × width
• Triangle: Perimeter = side1 + side2 + side3, Area = (base × height) / 2
• Circle: Circumference = 2 × π × radius, Area = π × radius^2
• Parallelogram: Perimeter = 2 × (side1 + side2), Area = base × height
4. Placement on the Base:
• Arrange the color paper representations of polygons on the base, leaving enough space for the formulas to be placed next to each polygon.
5. Labeling and Details:
• Use marker pens or sketch pens to label each polygon and its corresponding formula for perimeter and area.
6. Decorating the Model:
• Use markers or color paper to decorate the model and add more details to make it visually appealing.

Now, you have a perimeter and area formulas working model using cardboard and color paper. This model visually represents different polygons and their respective formulas for perimeter and area
