Area of a Rectangle: The area of a rectangle is the amount of space enclosed by its four sides. To find the area, you multiply the length of the rectangle by its width.

 For example, if a rectangle has a length of 5 units and a width of 3 units, you would multiply 5 by 3 to get an area of 15 square units. Perimeter of a Circle: The perimeter of a circle is the distance around its outer edge. To find the perimeter, you can use a special constant called pi (π) which is approximately 3.14159. Multiply the diameter of the circle (the distance across the circle passing through its center) by pi to get the perimeter.

 Alternatively, you can multiply the radius (the distance from the center to the edge) by 2 and then multiply it by pi. For example, if a circle has a diameter of 8 units, 

you would multiply 8 by pi to get a perimeter of approximately 25.13274 units. Area of a Triangle: The area of a triangle is half the product of its base and height. To find the area, you multipl

y the length of the base of the triangle by 

the perpendicular height and divide the result by 2. For example, if a triangle has a base of 6 units and a height of 4 units, you would multiply 6 by 4 and then divide the result by 2 to get an area of 12 square units. Perimeter of a Square: The perimeter of a square is the total length of its four equal sides. To find the perimeter, you simply multiply the length of one side by 4. 

For example, if a square has a side length of 7 units, the perimeter would be 7 multiplied by 4, which equals 28 units. These are just a few examples of plan geometry concepts. There are many more geometric shapes and formulas used to calculate various properties in geometry, but these examples should give you a good starting point
