Question 88134

 the sides of a triangle are represented by x , 3x and 3x+2 find each side if the perimeter is 37
       Let the first side of the triangle = a = x
          the second side of the triangle = b = 3x
          the third side of the triangle =  c = 3x+2
              perimeter of the triangle  =  p = 37
                                 p = sum of all the three sides of the triangle
                                 p = a+b+c
                                37 = x+3x+3x+2
                                37 = 7x+2
                                37-2 = 7x 
                                35 = 7x   or x= 35/7 = 5
    therefore the sides of the triangle are, first side = a = 5
                                            second side = b = 3.5 = 15
                                             third side = c =3.5+2 = 17.
