Find the perimeter of the rectangle whose:
$l e n g t h = 18 c m, b r e a d t h = 10 c m$

Open in App

Solution

Given $l e n g t h (l) = 18 c m$
$b r e a d t h = 10 c m$
The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape.
Perimeter of rectangle $= 2 (l + b)$
$= 2 (18 + 10) = 2 (28) = 56 c m$
Hence perimeter of rectangle is $56 c m$
