The sides of a triangular birdcage are consecutive integers. If the perimeter is 114 centimeters, what is the length of each side?

Call the consecutive integers n, n+1, and n+2. One you find n, you can find the other next two numbers.

n + (n + 1) + (n + 2) = 114

3n + 3 = 114

3n = 111

n = 37

Therefore, the three numbers are n (37), n+1 (38), and n+2 (39).
