The longest side of a trangle is 3 times the shortest side and the third side is 2 cm shorter than the longest side. If the perimeter of the triangle is at least 61 cm, find theminimum length of the shortest side. |

Answer» Solution :Let the minimum LENGTH of the shortest side be x cm. Then, the longest side `=3x cm` and the third side `=(3x -2)` cm. `therefore x +3x +(3x-2)ge 61 rArr 7X ge 63 rArr x ge 9`. Hence, the minimum length of the shortest side is 9 cm. |
