Answer 2

The perimeter of the triangle is `8 2/5`.

Explanation:

Determine the perimeter of a triangle with sides:

`1 3/5,` `3 1/5,` `3 3/5`

The perimeter of a triangle is the sum of the lengths of its three sides.

`P=1 3/5 + 3 1/5 + 3 3/5 =7 7/5`

Convert `7 7/5` to an improper fraction by multiplying the denominator by the whole number and adding the numerator, placing the result over the denominator.

`(5xx7+7)/5=42/5`

To determine the mixed fraction, divide the numerator by the denominator until you get a whole number with a remainder. (Use long division.)

`42-:5="8 r5"`

The whole number becomes the whole number of the fraction, the remainder becomes the numerator, and the denominator is `5`.

The mixed fraction is `8 2/5`.
