I'm assuming that the s stands for 5 so it would be 19.6
Step-by-step explanation:
The area of a triangle could be determined using the following formula

plug in the numbers



a = 126
The area of the triangle is 126 square meters
Irratonal numbers can't be written as a/b where a and b are integers and b≠0
so if it can be written in form a/b then it is not irrational

, it's rational
1/5 is rational

it's irrational because we can't simplify the square root further
6.3=6.3/1=63/100, rationanl
answer is

is irrational
