How to find length of a line

how i can find the length of this line in the x direction and in y direction

      line(newBoxPolygon(:, 1), newBoxPolygon(:, 2), 'Color', 'R');

This piece of code draws a rectangular polygon , can anyone tell me how to calculate the width and the height generated by this line. Thank you

Let X = newBoxPolygon(:, 1) and Y = newBoxPolygon(:, 2), then

width = max(X) - min(X)
height = max(Y) - min(Y)
