Perimeter of a Parallelogram

Area (A)=ah $(A) = ah$
Perimeter (P)=2a+2b $(P) = 2a + 2b$

Example :
I know that for a parallelogram a = 9 , b = 22 and h = 14 . From this find out Area of the parallelogram.

Here a=9,b=22,h=14 (Given) $"Here " a=9, b=22, h=14" (Given)"$

Perimeter=2⋅(a+b) $"Perimeter" = 2 * (a + b)$

=2⋅(9+22) $= 2 * (9 + 22)$

=62 $= 62$

Area=a⋅h $"Area" = a * h$

=9⋅14 $= 9 * 14$

=126 $= 126$
