Let the third side be x.
The other two sides will be (2x - 5).
Given that perimeter = 55m:
(2x - 5) + (2x - 5) + x = 55
2x - 5 + 2x - 5 + x = 55
5x - 10 = 55
5x = 65
x = 13
Find the length of each side:
The third side = x = 13
The two other sides = 2x - 5 = 2(13) - 5 = 21
Answer: The length of the sides are 21m, 21m and 13m
