let 4-5√3 be a rational number.
4-5√3= a/b where a and b are co primes
-5√3=a/b-4
-5√3=a-4b/b
a-4b/b+5=√3
But this contradiction is wrong therefore 4-5√3 is a irrational number.
Hope this will help you.

Answer: 550m^2 is the CSA and cost of painting is ₹22,000
Step-by-step explanation:
r=7 h= 9m
CSA= 2πrh+πr^2
πr(2h+r)
22/7×7(2×9+7)
22×25
=550
cost of painting=₹40×550m^2
=₹22,000
