The perimeter is 20 units
Step-by-step explanation:
The end-point of a side of square can be used to calculate length of a side. And the side will be used to calculate the perimeter.
Given
(3,-1) and (7,2)
Let
(3,-1) = (x1,y1)
(7,2) = (x2,y2)
We have to calculate the distance
The formula for distance is:
Let s be the side of a square
then,
The side of square is 5 units. Then,
The perimeter is 20 units

Answer: He travels 280 miles.
Step-by-step explanation:
Speed = Distance / Time
Distance = speed x time
Distance covered at first 2 hours at 55 mph
= distance = 55 X 2= 101 miles
Distance covered in next hour at 70mph
Distance = 70 x 1= 70 miles
Distance covered in the last 2 hours at 50mph
Distance = 50 x 2= 100 miles
Total distance traveled = 110+70+ 100= 280 miles.
