Answer:
its 30
Thats my solving process , As its scalene triangle so use its formula
perimeter of triangle= a+b+c
Step-by-step explanation:
Let the sides lengths of the triangle be a, band c respectively
given ,
a= 8
b= 10
c = 12
To find : perimeter of the triangle = ?
We know ,
Perimeter of triangle = a+b+c
= 8+10+12
= 30 cm²
therefore, the perimeter of the given triangle is 30 cm ² .
