Answer:
Perimeter is the boundary of an object (except for circle).
Perimeter of square is 4x side.
Perimeter of Rectangle is 2(L+B)
Perimeter of Triangle (irrespective of it's type) is Sum of all sides.
Step-by-step explanation:
All the sides of Square are equal so 4x side.
For eg. 2 cm each side so 2x4= 8cm
Opposite sides of Rectangle are equal so 2(L+B)
For eg. 2cm each length and 4cm each breadth so 2(L+B)= 2(2+4)= 2x6= 12cm.
Perimeter of Triangle is Sum of all sides.
