Two legs of a triangle have lengths of 7.4 and 17.3 respectively. Given that the length of the third side is a whole number, what is the largest possible length for the third side?
Three positive integers \(a, b\) and \(c\) are the side lengths of \(\triangle ABC.\) If \(c\) is the longest side and \(a + b + c = 21,\) what is the maximum value of \(c?\)
Two of the legs of an isosceles triangle have length 12 and 27 respectively. What is the perimeter of the triangle?
