A brick walk 2 m wide surrounds a rectangular pool that is 3 m by 5 m Find the area of the walk?

Answer 1

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.
