Question

Find the perimeter of each of the following closed figures:

Answer 1

Step 1: Calculating the perimeter
We know that, The perimeter of the figure is the sum of all the sides of the given figure.
In the given figure we have,

$AB=FE=15cm$
$DC=GH=10cm$
$DE=AH=25cm$
$BC=GF=5cm$
The perimeter of the above figure is:
$=AB+BC+CD+DE+EF+FG+GH+HA$
$=15+5+10+25+15+5+10+25$
$=110cm$

Therefore, the perimeter of the given figure is $110cm$.
