Answer:
Sides of the triangular birdcage are 37 cm, 38 cm, 39 cm.
Explanation:
In the given triangular birdcage, sides of the triangle are consecutive integers.
Let sides of the triangle are x, (x + 1), (x + 2) cm.
Perimeter of a triangle = Sum of all sides of the given triangle
114 = x + (x + 1) + (x + 2)
114 = 3x + 3
3x = 111
x =

x = 37
Therefore, sides of the triangular birdcage are 37 cm, 38 cm, 39 cm.
