Let the first side be triangle be x Then second side of a triangle = x+3 and accordingly third side = 2x Perimeter of the triangle = sum of all the sides = 47 x+x+3+2x = 47 4x+3 = 47 Subtracting 3 from either side results in.. 4x+3-3 = 47-3 4x= 44 Dividing both sides by 4 x=11 So second side of a triangle = x+3 = 11+3 Ans : 14 meter

there is no formula...except maybe that perimeter = sum of 3 sides
