Question 550584
Pythagoras theorem states that						
The diagonal and the sides of the pool	form a right triangle		
Hypotenuse ^2= leg1^2+leg2^2						
						
leg1 = 	12.5	m				
Leg2^2=	10.5	m				
						
Diagonal ^2=	12.5	^2	+	10.5	^2	
Diagonal ^2=	156.25	+	110.25			
Diagonal ^2=	266.5					
take the square root						
Diagonal=	16.3	m
