Question 873807: A triangle has a perimeter of 91 inches. Find the length of the three sides if one side is 31 inches longer than the shortest side and the length of the third side is four times the shortest side. Answer by harpazo(655) (Show Source):
You can put this solution on YOUR website! The three sides:
x
x+31
4x
Perimeter is 91.
91 = x + x + 31 + 4x
91 = 6x + 31
91 - 31 = 6x
60 = 6x
60/6 = x
10 = x
The three sides are 10, 41 and 40.
