Answer:
The approximate length of the diagonal walkway is 21.21 meters
Step-by-step explanation:
we know that
Applying the Pythagorean Theorem in the square park, find out the the approximate length of the diagonal walkway
so
[tex]c^2=a^2+b^2[/tex]
where
c is the diagonal of the square
a and b are the length sides of the square
we have
[tex]a=15\ m\\b=15\ m[/tex]
substitute
[tex]c^2=15^2+15^2\\c^2=450\\c=21.21\ m[/tex]
therefore
The approximate length of the diagonal walkway is 21.21 meters
