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#.
