Answer:
53 yards
Explanation:
The Pythagorean theorem says the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse. A diagonal cuts a rectangle into to right triangles. The sides of the rectangle constitute the legs of the right triangle, and the diagonal of the rectangle is the hypotenuse.
Since ...
d² = 45² + 28²
then ...
d = √(45² +28²) = √2809 = 53 . . . . yards
The length of the diagonal path is 53 yards.
