It is necessary to find the perimeter of the KMP, if the length of the sides of the KM is 5 cm 8 mm, the sides of the MP are 1 cm 5 mm longer than the sides of the KM, but shorter by 2 cm 3 mm of the side of the PK.

1. Let us calculate what the side of the MR is equal to in a given triangle, if it is known that it is 1 cm 5 mm longer than the side of the CM, which in turn is equal to 5 cm 8 mm.

1 cm 5 mm = 1.05 cm.

5 cm 8 mm = 5.08 cm.

1.05 + 5.08 = 6.13 cm.

2. Next, we find out what the side of the RK is equal to, if we know, one hundred side of the MR is 2 cm 3 mm, shorter than it.

2 cm 3 mm = 2.03 cm.

6.13 + 2.03 = 8.16 cm.

3. Now we find out what the perimeter of the CMR triangle is equal to. To do this, we calculate the sum of the lengths of all its sides.

P = 5.08 + 6.13 + 8.16 = 19.37 cm or 19 cm 37 mm.

Answer: The perimeter of the KMR triangle is 19 cm 37 mm.
