The total number of 2-foot square tiles does it take to tile the border of the pool is [tex]2s\sqrt{2}[/tex] and this can be determined by using the formula of the perimeter of the square.
Given :
A square pool has a side length of s feet.
The following steps can be used in order to determine the total number of 2-foot square tiles does it take to tile the border of the pool:
Step 1 - The formula of the perimeter of square can be used in order to determine the total number of 2-foot square tiles does it take to tile the border of the pool.
Step 2 - The formula of the perimeter is given below:
P = 4L = 4s feet
where L is the length of the side of the square pool.
Step 3 - Now, the side length of the square tile is given below:
[tex]\rm a^2=2[/tex]
[tex]a = \sqrt{2}[/tex]
Step 4 - Now, the total number of 2-foot square tiles does it take to tile the border of the pool is:
[tex]=\dfrac{4s\sqrt{2} }{2}[/tex]
[tex]=2s\sqrt{2}[/tex]
