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
I hope I helped! I will be glad, if you mark my answer brainliest
Answer:
4.5 + pi (3.14) is a rational because it is a terminating decimal. irrational because it is a non-terminating and non-repeating decimal.
hope this helped!
378
Because a multiple of both 7 and 3 is 21, and 21*18=378.

Ans: Rational
----------------
2.) Is -1.2 repeating decimal rational or irrational?
Every repeating decimal is rational.
Every non-repeating decimal is irrational.
All whole numbers are rational.
All fractions are rational.
nth roots of a^k are irrational unless k is a multiply of n.
Example: The cube root of 3^6 is rational but the cube root of 3^5 is not.
