The second side of a triangle is 3 more meters than the first side. The third side is twice more than the first side. If the perimeter of a triangle is 47 meters, find the length of the second side.

Question

anonymous · Answer

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
