Question

If the door to the library is at (2, 4), the door to the mall is at (8, 2), and one

square unit equals one square mile, the approximate distance between the library

and the mall is

miles, when measured door to door.

Answer 1

6 miles

Explanation:

The distance formula is expressed as;

D = √(x2-x1)²+(y2-y1)²

D = √(2-4)²+(8-2)²

D = √(-2)²+(6)²

D = √4 + 36

AD = √40

AD = 6.32

Hence the approximate distance between the library and the mall is 6 miles
