One of the parties of a triangle of 83.6 cm, the second is 14.8 cm longer than the first, and the third is 8.6 cm longer than the second. Find triangle perimeter

75
The first party - 83.6 cm, the second is 14.8 cm longer than the first, i.e. 83.6+14.8=98.4 cm, the third is 8.6 cm longer than the second, i.e. 98.4+8.6=107 cm Perimeter - it is the sum of lengths of all parties: 83.6+98.4+107 = of 289 cm
