Question

find the perimeter.
write your answer as a fraction or as a whole or mixed number.

millimeters

Explanation:

Step1: Identify the side length

The triangle is equilateral with each side $2\frac{2}{3}$ mm. First, convert the mixed number to an improper fraction: $2\frac{2}{3}=\frac{2\times3 + 2}{3}=\frac{8}{3}$ mm.

Step2: Calculate the perimeter

Perimeter of a triangle is the sum of its three sides. Since all three sides are equal, perimeter $P = 3\times\frac{8}{3}$.

Step3: Simplify the expression

$3\times\frac{8}{3}=8$ (the 3 in the numerator and denominator cancels out).

Answer:

$8$
