Answer:
55.9 m
Explanation:
The pool measures;
Length = 50 m
Width = 25 m
Now, swimming from one corner to the other means swimming from end of length to end of width which will form a right angle triangle.
So the distance one will swim can be denoted by d and solved using pythagoras theorem.
Thus;
d = √(50² + 25²)
d = √(2500 + 625)
d = √3125
d = 55.9 m
