Answer 2

Answer:

THE ANSWER IS 5.5cm.

Step-by-step explanation:

*As  it as an equilateral triangle its all the three sides equal.

*Perimeter is the addition of all the three sides of a triangle.

                                               OR

*The formula of the perimeter of an equilateral triangle is:

                                       Perimeter= 3a

SOLUTION:  Given,

                                   Perimeter= 16.5cm

                                             3a= 16.5cm

                                                a=  $\frac{16.5}{3}$

                                                a = 5.5cm

Therefore, the length of one side is 5.5cm.
