Answer:
48.3 cm is the lower and upper bound of the perimeter.
Step-by-step explanation:
For any equilateral triangle, by definition, the
lengths of the sides of the triangle are the same.
Thus, the perimeter of the triangle is 16.1 + 16.1 + 16.1 = 3(16.1) = 48.3 cm.
Thus, the upper and lower bounds are the same and are both equal to
48.3 cm.
