Let’s first calculate the second side of the triangle. By condition, it is 13 cm less than this one:
25 – 13 = 12 (cm).
The sides cannot be in total less than the base, therefore, in our case, a possible option is when the base is 12 cm, and the sides are 25 cm each.
Let’s calculate its perimeter:
P = 12 + 25 + 25 = 62 (cm).
Answer: the perimeter of the given triangle is 62 cm.
