Answer:
300 yd saved
Step-by-step explanation:
The length of the diagonal of the field is found using the Pythagorean Theorem and is
d = √( 450 yd)² + ( 600 yd)² ) = √562500 yd² = 750 yd is the diagonal distance. If, on the other hand, the farmer walks the length and width of the perimeter of the field, that would be 450 yd + 600 yd, or 1050 yd.
The farmer could spare himself 1050 - 750, or 300 yd, of walking if he crosses the field along a diagonal.
