Answer:
8 cm , 19 cm , 25 cm
Explanation:
the perimeter (P) is the sum of the 3 sides of the triangle.
given P = 52 , then
x + 2x + 3 + 3x + 1 = 52
6x + 4 = 52 ( subtract 4 from both sides )
6x = 48 ( divide both sides by 6 )
x = 8
2x + 3 = 2(8) + 3 = 16 + 3 = 19
3x + 1 = 3(8) + 1 = 24 + 1 = 25
the lengths of the 3 sides are 8 cm , 19 cm , 25 cm
