36/3 = 12
Try that plus the even numbers just below and just above 12.
The length of the sides of a triangle are three consecutive even integers. The perimeter of the triangle is 36 in. What is the length of the longest side of the triangle?
2 answers
let 3 sides be x, x+2, and x+4
x + x+2 + x+4 = 36
3x = 30
x = 10
sides are 10, 12 and 14
x + x+2 + x+4 = 36
3x = 30
x = 10
sides are 10, 12 and 14
