In triangle ABC, the side is 6cm 4mm, this side is 12mm shorter than side BC and 1cm 6mm longer than side AC, the perimeter of the triangle is calculated.
Since 6 cm 4 mm = 64 mm, the length of the BC side will be:
64 + 12 = 76 mm.
Since AB is 1 cm longer than AC 6 mm = 16 mm, then AC wound:
64 – 16 = 48 mm.
By definition, the perimeter is the sum of all sides, then it is equal to:
64 + 76 + 48 = 188 mm.
Answer: The perimeter of triangle ABC is 18 cm 8 mm.
