Open in App

Solution

Step1: Finding the perimeter of a rectangle

We have:
Length of the rectangle $= 40 c m$ and
Breadth of the rectangle $= 35 c m$

The perimeter of the rectangle is given by $= 2 (L e n g t h + B r e a d t h)$
$= 2 (40 c m + 35 c m)$
$= 2 (75) c m$
$= 150 c m$
Therefore, the perimeter of the given rectangle is 150 cm.
