In the MFK triangle, the FK side is 62 cm, the KM side is 1 dm2. larger than the FK side, and the MF side by 16

In the MFK triangle, the FK side is 62 cm, the KM side is 1 dm. larger than the FK side, and the MF side by 16 cm smaller than the FK side. Find the perimeter of the triangle MFK.

1) What is the length of the CM side? If… more, then you need to add.

62 cm + 1 dm = 62 cm + 10 cm = 72 cm (1 dm = 10 cm)

2) What is the length of the MF side? If… less, then you have to subtract.

62 – 16 = 46 (cm)

3) What is the perimeter of triangle MFK? The perimeter of a triangle is equal to the sum of the lengths of its three sides.

P = 62 + 72 + 46 = 180 (cm)

180 cm = 18 dm

Answer. 18 dm.
