The first side of the triangle is 2 3/20 meters, the second is 5 times larger than the first, and the third is 3/10 more than the second. Find the perimeter of the triangle.

Find the length of the second side of this triangle.

According to the condition of the problem, the first side of this triangle is 2 3/20 meters, and the second side of this triangle is 5 times larger than the first.

Since 2 3/20 = 2.15, the length of the second side of this triangle is:

5 * 2.15 = 10.75 m.

Find the length of the third side of this triangle.

According to the condition of the problem, the third side of this triangle is 3/10 larger than its second side, therefore, the length of the third side of this triangle is:

10.75 + 0.3 = 11.05 m.

We find the perimeter P of this triangle:

P = 2.15 + 10.75 + 11.05 = 23.95 m.

Answer: the perimeter of this triangle is 23.95 m.
