The three sides of a triangle are x+1 , 2x-1, and 2x +1 respectively and the perimeter is 26 cm. The length of the smallest side is - Correct Answer 6 cm

Given , the three sides of a triangle are = x + 1 , 2x - 1 and 2x + 1 = 26 ⇒5x + 1 = 26⇒5x = 26 - 1⇒5x = 25⇒x = 255.'.x = 5.'. x + 1  = 5 + 1 = 6.'. 2x - 1 = 2×5 - 1 = 10 - 1 = 9.'. 2x  + 1  = 2×5 + 1  = 10 + 1 = 11The Length of the smallest side is  = 6
