Question

workers are setting up the stage of the concert .the stage of is in the shape of the triangle . the side of the triangle are consecutive even numbers . If the perimeter of the stage i 168, what is the length of each side

Answer 1

You find perimeter by adding all of the sides, which in this case is only 3 because it is a triangle.  You also have to find consecutive even numbers.  I don't know exactly how to tell you to find the answer, but what I did was divide 168 by 3, which gave me the number 56. By adding the even numbers on both sides of 56, I found the answer.  The answer is 54, 56 and 58, when added equal to 168.

Answer 2

Lets divide 168/3 = 56. Subtract 2 to get the shortest side and add two to get the longest side.
54+56+58 = 168
