First add the extra 4 meters to both the length and width of the rectangular pool.
So now you have an area 7 meters by 9 meters (don't forget the walk is surrounding the pool; not just on two sides).
Calculate the area which is 63 meters squared = 9 * 7.
Since you only want the are of the walk, just subtract the area of the rectangular pool by itself without the brick walk added,
3 * 5 = 15 meters squared.
Now just subtract the area of the pool plus the brick walk and the area of the pool itself,
63 - 15 = 48 meters squared.
Which is your answer.

How do you calulate the surface area of the brick and its volume?
To calculate the surface area of a brick, you would find the surface area for each of the 6 sides, then add them together. To find the surface area of one of the faces/sides, you would multiply the length of the face in question by the width of that same face. If this is a regular brick, then the sides should match up, meaning if you do one side, then the opposite side should be the same surface area. To find the volume, you multiply the height of the brick by the length of the brick by the width of the brick.
