| **Find the perimeter of the KMP triangle, if the length of the CM side is 5 cm 8 mm, the MP side is 1 cm 5 mm longer than the CM side, but shorter by 2 cm 3 mm of the PC side.**

Given:

KM = 5 cm 8 mm;

MР = 1 cm 5 mm longer than the side of the CM;

PK = 2cm 3mm larger than the MP side;

Find the perimeter of the triangle.

To find the MP side: 5 cm 8 mm + 1 cm 5 mm = 7 cm 3 mm (MP side)

To find the side of the РK: 2 cm 3 mm +7 cm 3 mm = 9 cm 6 mm (side of the РK)

The perimeter of the figure is the sum of the lengths of all sides of the figure. The formula for finding the perimeter is: P = KM + MР + РK = 5 cm 8 mm + 7 cm 3 mm + 9 cm 6 mm = 22 cm 4mm

Answer: the perimeter of the triangle is 22 cm 4mm
