| 1) Find the length of the second side of the pentagon.
Add the difference to the length of the first side.
3.4 + 1.8 = 5.2 cm.
2) Determine the length of the third side.
5.2 + 1.8 = 7 cm.
3) Find the length of 4 sides.
7 + 1.8 = 8.8 cm.
4) Determine the length of the 5th side of the figure.
8.8 + 1.8 = 10.6 cm.
5) Find the perimeter of the pentagon.
To do this, we summarize the values of all its sides.
3.4 + 5.2 + 7 + 8.8 + 10.6 = 35 cm.
Answer:
The perimeter of the pentagon is 35 cm.
