    perimeter of a triangles are 12cm and 29cm respectively.

    Step-by-step explanation:

    finding the perimeter of a triangle simply means that you are finding the distance around. The simplest way to find the perimeter of a triangle is to sum up all its sides.

    mathematically,

    perimeter of a triangle = side A + side B + side C

    perimeter of a triangle = 3cm + 4cm + 5cm

    perimeter of a triangle = 12cm

    for the second triangle according to the question

    it says the triangle has sides, 7cm, 10cm, 12cm

    perimeter of a triangle = 7cm + 10cm + 12cm

    perimeter of a triangle = 29cm
