The lengths of the sides of a triangle are in the ratio of 3 to 5 to 6 . If the perimeter of the triangle is 70, what is the length of the longest side ? Correct Answer 5

Let, the side of a triangle are 3x, 5x, and 6x According to the question 3x + 5x + 6x = 70 14x = 70 x = 5 Total length of the longest side = 6x = 6×5 = 30
