PARALLELOGRAM
Formula for the perimeter of a parallelogram = 2(a+b) ('a' means side and 'b' means base)
Formula for the area of a parallelogram = $$b*h$$ ('b' means base and 'h' means height)
Let us work it out with an example:-
1. Find the area and perimeter of a parallelogram if breadth is 3cm and height is 5cm and the third side is 9cm.
SOLUTION:-
Area =3*5 = 15cm
Perimeter = 2(9+3) = 24cm.
