Answer 2

Answer:

Let the smallest side of the triangle be x cm.

From the given information,

x =

Biggest side = 3x+15

Also, x =

Third side = 2x+6

Perimeter of triangle = Smallest side + biggest side + third side

Perimeter = x+ (3x+15) + (2x+6) = 39

6x +21 = 39

6x = 39-21

6x = 18

x = 3

Smallest side = 3 cm

Biggest side = 3x+15 = (3×3)+15 = 24 cm

Third side = 2x+6 = (2×3) + 6 = 12 cm
