Answer:
Perimeter of the triangle is 48.
Step-by-step explanation:
First, you need to calculate all sides of the triangle. You know two of them and you can use Pythagoras Theorem for calculating the third side. Pythagoras Theorem is a²+b²=c²
Here, you know a and b. So 12²=144 ; 16²=256
144+256=400
Now, you need to find root.
√400=20
The third side (c) is 20.
Now you add up all sides.
20+12+16=48
