Rectangle:
The perimeter is the sum of the four sides.
The area is the product of the base x height.
Circle.
The perimeter is the diameter multiplied by Pi (3.1416)
The area is Pi multiplied by the radius square. (Pi* (r*r))

Fro the perimeter you add all the sides (for rectangles) and the area by multiplying the length and width.

Let rectangle be of length L and breadth B
P = 2L + 2B
P = 2.(L + b)
A = LB
For circle of diameter , d and radius , r:-
C = Ï d = 2 Ï r
A = Ï.r²
