This warning message indicates that there is an issue with the calculation of the square root of a negative number, which is not a valid operation. The code is trying to calculate the distance between two objects based on their actual size and their size in pixels, using the focal length of the camera. However, the calculation is resulting in a negative number for the actual area or the pixel area, which is causing the error. To fix this issue, you may want to check the input values and make sure they are valid before performing the calculation
