In triangle ABC, side AB is 6 cm 4mm. This side is 12mm shorter than the BC side and 1cm 6mm longer than the speaker side. Calculate the perimeter of the triangle.

To calculate the perimeter of a triangle, you must first find its sides.

Find the side of the BC-it is 12 mm longer than the side AB.

AB = 6 cm 4 mm = 64 mm.

BC = 64 + 12 = 76 mm.

Now we find the side of the AC, it is 1 cm 6 mm shorter than AB.

1 cm 6 mm = 16 mm.

AC = 64 – 16 = 48 mm.

Now we are looking for the perimeter.

P = 64 + 76 +48 = 188 mm = 18 cm 8 mm.

Answer: The perimeter of the triangle is 18 cm 8 mm.
