One side of the triangle is 2cm longer than the second side. The third is 3/5 as long as the first side. If the perimeter of the triangle is 24cm, Find the lengths of the three sides.

Answer 1

first side --- x
second side --- x-2
third side -- (3/5)x

x + x-2 + (3/5)x = 24
times 5

5x + 5x-10 + 3x = 120
13x = 130
x = 10

first side = 10
2nd side = 8
3rd side = 6
