Question

Find the perimeter of each of the following closed figures:

Answer 1

The perimeter of the closed figures can be calculated as follows
Perimeter $=$ Sum of all sides
$\left(i\right)$ Perimeter $=AB+AC+CD+DG+GH+FH+EF+BE$
$=15+6+10+25+15+5+10+25$
$=110cm$
Therefore, the perimeter of the closed figure $=110cm$
$\left(ii\right)$ The perimeter of the closed figures can be calculated as follows
Perimeter $=$ Sum of all sides
Perimeter $=AB+AC+CD+DG+BF+EF+EH+GH$
$=20+4+8+20+4+8+20+4$
$=88cm$
Therefore, the perimeter of the closed figure $=88cm$
