Answer:
15.49 approx
plz mark brilliant
Step-by-step explanation:
You can clearly see the base angle is 90, hence it's forming a right angled triangle! let's find out the base which will be considered as the length of pool putting Pythagoras theorem, Hypotenuse^2 = Base^2 + Height^2 16^2 = Base^2 + 4^2 256 = Base^2 + 16 Base^2 = 256 - 16 Base^2 = 240 Base = √240 = 15.49 approx
