In the MFK triangle, the FK side is 62cm, the KM side is 1 in. Longer than the FK side, and the MF side is 16cm

In the MFK triangle, the FK side is 62cm, the KM side is 1 in. Longer than the FK side, and the MF side is 16cm less than the FK side. Find the perimeter of the triangle MFK and express it in decimetres.

Let me remind you: 1dm = 10cm
FK = 62 cm;
KM is 10cm more than FK, which means KM = 62 + 10 = 72 (cm)
MF is 16cm smaller than FK, so MF = 62-16 = 46 (cm)
Perimeter is the sum of the lengths of all sides.
The perimeter is 62 + 72 + 46 = 180 (cm)
Expressed in dm: 180cm = 18dm
Answer: 18dm.
