Answer:
48 cm
Step-by-step explanation:
The perimeter of the figure is the sum of the lengths of its sides.
Find the length of the unknown side
Let the unknown length be x cm.
Notice that the sum of the lengths of the unknown side and the side measuring 5 cm I equal to the length of the side measuring 9 cm.
x +5= 9
<em>Subtracting 5 from both sides:</em>
x= 9 -5
x= 4
Add up the lengths of all of the sides to find the perimeter. I will add the lengths starting from the side measuring x cm (or 4 cm), and sum them up in a clockwise manner. This ensures that none of the sides are overlooked.
Perimeter of the figure
= 4 +15 +9 +7 +5 +8
= 48 cm
