2. Calculate the length of a side of an equilateral triangle if the perimeter is:

A. 15 cm
B. 24 cm
C. 36 cm
D. 45 m
E. 900 m
F. 270 mm

To find the length of a side of an equilateral triangle, divide the perimeter by 3, since all three sides are equal in length.

A. 15 cm / 3 = 5 cm
B. 24 cm / 3 = 8 cm
C. 36 cm / 3 = 12 cm
D. 45 m / 3 = 15 m
E. 900 m / 3 = 300 m
F. 270 mm / 3 = 90 mm
