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.
