Question 231426: Find the perimeter of a triangle if one side is 11 centimeters, another side is two-fifths the perimeter and the third side is one half the perimeter. Answer by unlockmath(1688) (Show Source):
You can put this solution on YOUR website! Hello,
Let x be the total perimeter,then we can set up an equation.
11 + 2/5(x) + 1/2(x) = x Let's multiply 10 so to get rid of the fractions.
110 + 4x + 5x = 10x Now, subtract 9x from both sides.
110 = x This gives us the total perimeter.
11 cm is one side (given)
44 cm is another side
55 cm is the other side These should add up to 110 cm
