Glen is planting square flower gardens surrounding a triangular fishpond as shown. If the sides of the triangular fishpond are 5 ft and 9 ft, how long is the hypotenuse of the pond?

Answer:
[tex]\sqrt{106}\ ft[/tex]
Step-by-step explanation:
we know that
Any right triangle, must satisfy the Pythagorean Theorem
so
[tex]c^2=a^2+b^2[/tex]
where
c is the hypotenuse (greater side)
a and b are the legs (perpendicular sides)
substitute the given values
[tex]c^2=5^2+9^2[/tex]
[tex]c^2=106[/tex]
[tex]c=\sqrt{106}\ ft[/tex]
