Calculate the perimeter of the pentagon if its smallest side is 3.4 cm and each other is 1.8 cm larger than the preliminary one.

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.
