given:
units
The length of the sides form an arithmetic sequence.

let be the shortest side therefore the first term
let be the common difference
the series is therefore:
, ,
then





all possible sets of the lengths of the sides of the triangle:

if and , then the lengths of the sides of the triangle are


.........first solution: possible sides are ,,and
if and , then the lengths of the sides of the triangle are


.........2nd solution: possible sides are ,,and
if and , then the lengths of the sides of the triangle are


.........3rd solution: possible sides are ,,and
if and , then the lengths of the sides of the triangle are


.........4th solution: possible sides are ,,and
if and , then the lengths of the sides of the triangle are


.........5th solution: possible sides are ,,and
if and , then the lengths of the sides of the triangle are


.........6th solution: possible sides are ,,and
if and , then the lengths of the sides of the triangle are


.........7th solution: possible sides are ,,and
if and , then the lengths of the sides of the triangle are


.........8th solution: possible sides are ,,and
if and , then the lengths of the sides of the triangle are


.........9th solution: possible sides are ,,and
