The longest side of a triangle 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,What is the minimum length of the shortest side?	Answers: A) 8cm B) 9cm C) 10cm D) 11cm E) 12cm
let the shortest measurement be x cm   then the largest side will be 3x cm   and the third side will be (3x-2)cm   now according to the problem   x+3x+3x-2 &gt;=61   7x-2 &gt;= 61   7x &gt;= 63   therefore x&gt;=9cm   ANSWER:9cm
