The sides of a triangle are 3: 4: 5, find the sides of a similar triangle. the perimeter is 36.

1. Let’s find how many parts make up the sides of the triangle:

3 + 4 + 5 = 12 pieces.

2. Find the length of one part by dividing the perimeter by the number of parts:

36/12 = 3.

3. Find the length of each side by multiplying the number of side parts by the length of one part:

1 side = 3 * 3 = 9,

2 side = 4 * 3 = 12,

3rd side = 5 * 3 = 15.

Answer: The sides of the triangle are 9, 12 and 15.
