The distance between points (3, 7) and (x1,y1) is the square root of (x1 - square root of 3) (y1 - 7)square

The distance between two points with coordinates (x₁,y₁) and (x₂,y₂) is calculated through the equation,
                          distance = sqrt ((x₂ - x₁)² + (y₂ - y₁)²))
We can see that the equation given in this item is very similar to what I have written above only that the (x₂,y₂) is replaced with (3,7).
