Question 343320
Firstly, we have to find the area of the tiles laid.
..
Area of tiles laid = Total area ( including tiles ) - the area of the pool.
..
Area of pool = 16 * 40 = 640 sq.ft.
..
The tile is 1 foot in length and width.
add 2 to length & width of pool
the width = 16+2 = 18
the length = 40 +2 = 42
Total Area including tile Area = 18*42= 756 sq. ft
...
Area of tiles = 756-640=116 sq.ft.
..
one tile is 1*1 = 1 sq. ft.
area = 116 sq.ft
Number of tiles = 116.
