Find the perimeter of the triangle KMP, if the length of the KM side is 5cm 8mm, the MP side is 1cm5mm

Find the perimeter of the triangle KMP, if the length of the KM side is 5cm 8mm, the MP side is 1cm5mm longer than the KM side, but shorter by 2cm 3mm than the PK side.

We will solve this task in steps and explain each of them in detail.
1) 58 + 15 = 73 millimeters – the length of the MR side, since its length is 1 centimeter 5 millimeters longer than the CM side, and the CM side is 5 centimeters 8 mm;
2) 73 + 23 = 96 millimeters – the length of the side of the RK, since its length is 2 centimeters 3 millimeters longer than the side of the MR, and the length of the MR is 73 millimeters;
3) 58 + 73 + 96 = 227 millimeters = 22 centimeters 7 millimeters – the perimeter of the CMR triangle.
Answer: 22 centimeters 7 millimeters.
