In the pentagon ABCDE, the smaller side AB is 3 m, and each next side is 2 m larger

In the pentagon ABCDE, the smaller side AB is 3 m, and each next side is 2 m larger than the previous one. Find the perimeter of the pentagon.

To calculate the perimeter of a given ABCDE pentagon.

First, you need to calculate the lengths of all sides of the pentagon, if the problem statement says,

that the smaller side is 3 meters, and each next side is 2 meters larger than the previous one.

So we need to add (2) to (3), and add (2) to the result, and so on:

1). 3 + 2 = 5;

2). 5 + 2 = 7;

3). 7 + 2 = 9;

4). 9 + 2 = 11.

The result of the calculation is:

AB = 3 m.

BC = 5 m.

СD = 7 m.

DE = 9 m.

EA = 11 m.

Now we can calculate the perimeter of the pentagon:

1). 3 + 5 = 8;

2). 8 + 7 = 15;

3). 15 + 9 = 24;

4). 24 + 11 = 35.

Answer: The perimeter of the pentagon is 35 meters.
