Answer:
I cant help unless i have workable units (0.5) is not a point 
but im guessing that you were trying to say (0,5) in which case its 
7.07106781187 
its a triangle 
5 on one side 
5 on the other 
solve for the hypotenuse 
 hypotenuse = 
hypotenuse = 7.07106781187 
I hope this helps!

A = p q / 2
p = diagonal 1
q = diagonal 2
2A / q = p
Solve for p
180/18 = 10
        
             
        
        
        
By using the Pythagoras theorem, the length of the ladder will be 13.6 feet.
<h3>What is a Pythagoras theorem?</h3>
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as 
H² = P² + B²
Jennifer needs to use a ladder to clean a second-floor window on a building. 
If the window is 13 ft above the ground and the base of the ladder is 4 ft from the building.
Then the length of the ladder will be 
H² = 13² + 4²
H² = 169 + 16
H² = 185
H = 13.6 ft
