Answer:

220 km  

Step-by-step explanation:

Since the direction north is perpendicular to the direction east, the driver has covered the two legs of a right triangle.  The hypotenuse is his displacement for the combination of the two segments.

    D = √(215² + 45²)

        =  √(46,225 + 2,025)

        =  √48,250  =  219.6588... km

Nearest whole number:   220 km

A) The perimeter is the length around the rectangle, so it would be 2 + 5 + 2 + 5 = 14m

The area is 2m * 5m = 10m^2

b/c) You have to draw a rectangle with a perimeter of 14m, and an area that ISN'T 10m^2. You could draw a 3m by 4m rectangle which would have a perimeter of 14m and an area of 12m^2.
