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 ?
- A. 5
- B. 5
- C. 5
- D. 5
Answer: Option D
Explanation:
Let the sides of the triangle are
3x,5x and 6x
Given perimeter(3x + 5x + 6x) = 70
= > 14x = 70
∴ x = 5
So longest side of the triangle is 6
= 6×5 = 30
