Arectangular park is 9 miles long and 3 miles wide. how long is a pedestrian route that runs diagonally across the park?

9.4868

Step-by-step explanation:

This problem is solved with the Pythagorean theorem. If you divide the park into two pieces, you get two triangles with a right angle.

Phythagorean theorem states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

So, if the sides are 9 and 3, the other side is the square root of the sum of 9 and 3 squares (9 and 81 equals 90). And the square root of 90 is 9.4868
