#QUESTION#

Find the perimeter of a rectangle whose length is 12 cm and breadth is 8 cm.

#ANSWER#

$Perimeter \: is \: the \: sum \: of \: all \: sides \: of \: a \: figure.$

$Perimeter \: of \: rectangle = 2(l + b)unit.$

(Where l is length and b is breadth)

Given!!!

length of rectangle = 12cm

breadth of rectangle = 8cm

Applying the formula of perimeter of rectangle
=2(l + b)unit

$2(12 + 8) \: cm \\ \ \ \\ = 2(20)cm \\ \\ = 40 \: cm$

So the Perimeter of rectangle is 40 cm.
