Answer with explanation:
→A polygon is a simple closed curve. So , a closed curve occupies area.
⇒When we use the word area, it describes two dimensional closed geometrical object.It is not necessary that ,the shape is polygon only, it should be a simple closed curve.For,example, Circle, Combination of Part of curve and line segments, but it should be a closed curve.
⇒There are some open curves , which occupies area ,but the curve is not closed from both sides, so we can't predict it's area precisely.Therefore , open curves does not come into consideration when we use the word area.

Answer: 8 hours
Step-by-step explanation: You would first multiply 2 hours by 4 mph, and get 8 miles. You would then subtract 8 miles from 26 miles, and have 18 miles left. You would now divide 18 miles by 3, as he is now traveling 3 miles per hour and needs to travel 18 miles. You would get 6 hours. You would now add 6 hours by the 2 hours initially traveled at 4 mph, and get 8 hours.
