Respuesta :
The distance between city a and city b is square root {(x_2 - x_1)^2 + (y_2 - y_1)^2} where (x_1, y_1) is city a coordinates and (x_2, y_2) is city b coordinates.
Given,
Two cities a and b are mapoed on the coordinate plane.
We need to find the distance between them.
What is the distance between two points in a coordinate plane?
One point has (a,b) coordinates.
The other point has (c,d) coordinates.
The distance between them is given by:
square root {(c-a)^2 + (d-b)^2}
Let,
City a has (x_1, y_1) coordinates.
City b has (x_2, y_2) coordinates.
Find the distance between city a and city b.
Distance = square root {(x_2 - x_1)^2 + (y_2 - y_1)^2}
Thus the distance between city a and city b is square root {(x_2 - x_1)^2 + (y_2 - y_1)^2} where (x_1, y_1) is city a coordinates and (x_2, y_2) is city b coordinates.
