7.25*2=14.5
If each inch equals 2 feet you just need to multiply by the factor of (2)
(4) 64 tiles, (5)
, (6) 
Step-by-step explanation:
Given data: Side length of square tile = 1 ft
(4) Side length of square pool = 8 ft


= 64
Hence 64 tiles needed for the border.
(5) Suppose number of square tiles be N and side of square tub is s ft.
So, N = 

So, the expression is
.
(6) The equivalent expression is
.
