A perimeter means the distance of the boundary of a two dimensional shape. Also defined as the total sum of the length of all the sides of the object. The algebraic sum of length of each side is the perimeter of that area.
We have the formula available for the following shapes:
It is also defined as the total sum of the length of all the sides of the object. So, the algebraic sum of the length of individual sides of the object gives the perimeter of that object.
| Geometric Shape | Perimeter Formula | Metrics |
| Parallelogram | 2(Base + Height) | |
| Triangle | A + b + c | a , b and c being the side lengths |
| Rectangle | 2(Length + Width) | |
| Square | 4a | a =Length of a side |
| Trapezoid | a +b+c+d | A, b, c, d being the sides of the trapezoid |
| Kite | 2a + 2b | a = Length of first pair b = Length of second pair |
| Rhombus | 4 x a | a  = Length of a side |
| Hexagon | 6 x a | a  = Length of a side |
