Solution
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.
