Answer:
The exact dimensions of the park is 80 meters by 60 meters.
Step-by-step explanation:
Let the width of the rectangular park is W meters, then its length will be (W + 20) meters.
Now, given that the diagonal route is 40 meters shorter than the other route.
Hence,
⇒
Now, squaring both sides we get,
(2W - 20)² = W² + (W + 20)²
⇒ 4w² - 80W + 400 = 2W² + 40W + 400
⇒ 2W² = 120W
⇒ W = 60 meters
Now, length is (60 + 20) = 80 meters
Therefore, the exact dimensions of the park is 80 meters by 60 meters. (Answer)
