Find the perimeter of the triangle KMP if the side length. KM is 5cm 8mm

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

Let’s translate cm into mm and find the side of the MР, since it is 1 cm 5 mm longer than the side of the КM.

58 + 15 = 73 (mm) – MР.

Since MР is 2 cm 3 mm shorter than RK, then РK is 2 cm 3 mm larger than MР, from here we find РK:

73 + 23 = 96 (mm) – РK.

Now that we have found and know the values of all three sides, we will find the perimeter of the CMР triangle.

The perimeter is the sum of the lengths of all sides, therefore:

58 + 73 + 96 = 227 mm or 22 cm 7 mm – Perimeter (CMР).

Answer: 22 cm 7 mm.
