A square park with sides 15 meters in length has a diagonal walkway as shown.
Alexxandr [17]

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

c^2=a^2+b^2

where

c is the diagonal of the square

a and b are the length sides of the square

we have

a=15\ m\\b=15\ m

substitute

c^2=15^2+15^2\\c^2=450\\c=21.21\ m

therefore

The approximate length of the diagonal walkway is 21.21 meters
