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 .

If the two sides with length 3 and 4 are the two legs, then the missing side, i.e. the hypotenuse, is indeed 5.
But it could also be the case that 4 is the hypotenuse and 3 is one of the legs. In this case, the missing side is the other leg, so we calculate it using
So, a right triangle with legs and 3 has an hypotenuse of 4.
In both cases,
(as a consequence of the interesecting secant-tangent theorem)
So we have
10.
(omit the negative solution because that would make at least one of AB or AD have negative length)
11.
(again, omit the solutions that would give a negative length for either AB or AD)
