Mrs. Clarkson designed a rectangular garden with a length of 15 meters and a width of 8 meters. She plans to build a walkway through the garden from one corner to the next. What measure is closest to the length of the diagonal walkway?
Looks like a simple case of Pythagoras
d^2 = 15^2 + 8^2 = 289
d = √289 = 17 m
