Question

A square park has a diagonal walkway from one corner to another. If the walkway is 120 meters long, what is the approximate length of each side of the park?

Answer 1

85 m

Explanation:

The diagonal of a square is √2 times the length of the side. The park will have a side length of 120/√2 m ≈ 84.85 m, about 85 meters.

_____

The relations are ...

diagonal = (√2)×(side length)

side length = diagonal/√2 . . . . . . . . . divide the above equation by √2
