Description |
Figure |
| Rectangle | 2(Length + Breadth) | Length and breadth are the dimensions of rectangle |  |
| Square | 4x | Let x be the side of square |  |
| Triangle | a + b + c | a, b and c being the side lengths of triangle |  |
| Parallelogram | 2(Base + Height) | Base and Corresponding Height are the dimensions of rectangle |  |
| Rhombus | 4x | Let x be the side of rhombus |  |
| Kite | 2x + 2y | x = length of one pair, y = length of second pair |  |
Illustration: .Calculate the perimeter of a square with each side measuring 5 units.
Solution: given side length of square = 5 units
now we know that perimeter of a square = 4 X side
= 4 X 5
= 20 units
Illustration : .Calculate the perimeter of a triangle with each side measuring 4 cm
Solution: given sides of triangle are 4cm,4cm,4cm
Now we know that perimeter of a triangle with sides a,b,c = a+b+c
thus perimeter of given triangle = 4+4+4
= 12 cm
