While walking on a plane surface, a traveler first headed 19 miles north, then 16 miles west, then 3 miles south and finally 4 miles east. how many miles from the starting point was the traveler after these four legs of the journey?

20 Miles

Step-by-step explanation:

19 miles north and then 3 miles south is just 16 miles north.

16 miles west and then 4 miles east is just 12 miles west.

√16^2+12^2 = √256 + 144

√256+144 = √400

√400 = 20

The traveler is 20 miles from the original starting point.

(I honestly don't know why you'd use this formula, but it's what I was taught.)

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
