 Question 317216: One side of a triangle is 5 meters longer than the second side.The third side is four times the length of the second side.If the perimeter of the triangle is 65 meters,how long is the second side?Answer by texttutoring(324)   (Show Source): You can put this solution on YOUR website!Let x = the length of the second side The first side is 5 metres longer, so the first side is x+5 The third side is four times the length of the second, so it is 4x. Perimeter of a triangle, just add the 3 sides up: P = (x+5) + x + 4x 65 = 6x + 5 60 = 6x x = 10 The second side is 10 meters.
