hope you get the formulas

Answer 2

Perimeter Formula

       1.  Square:  

                   Perimeter = 4×s

          where s is the length of the side of the square.

       2. Rectangle:

                  Perimeter= 2 L +2 B  

Where L is the length and B is the breadth of the rectangle.

     3.   Triangle:  

                Perimeter = a + b + c  

Where a, b and c are the length of the sides of the triangle

   4. Circle

Perimeter $=2\pi r=\pi d$

Where r is the radius and d is the diameter of the circle

  5. Right triangle:

        Perimeter=$a+b+\sqrt{a^2 + b^2}$  

    Where a and b are the length of two legs of the triangle  

Area Formula

1. Square:  

Area= s×s  

    Where s is the length of the side.

2. Rectangle:

Area=L×B  

Where L is length and B is Breadth

3. Triangle:  

Area =$\frac{1}{2}$×B×H  

Where B is the Base and H is the Height

4. Parallelogram:

Area=b×h  

Where b is the base and h is the height  

5. Trapezoid:

Area=$\frac{b^1+b^2}{2}$×h

Where b1 and b2 are the lengths of the parallel sides and h is the distance between the parallel sides.

6. Circle:

Area=$\pi r^2$

Where r is the radius
