Answer #1

(1) Let the three sides of the triangle be x, x + 2 and x + 4.
According to the problem,

Therefore, the three sides of the triangle are 104, 106 and 108.


(2) Let the three sides of the triangle be x, x + 1 and x + 2.
According to the problem,

Therefore, the three sides of the triangle are 161, 162 and 163.
