Answer:

12 pavers

Step-by-step explanation:

step 1

Find out the area of one square paver

The area of a square is

[tex]A=s^{2}[/tex]

where

s is the length side of the square

we have

[tex]s=2\ ft[/tex]

substitute

[tex]A=2^{2}[/tex]

[tex]A=4\ ft^{2}[/tex]

step 2

Find out the area of the rectangular patio

we know that

The area of a rectangle is

[tex]A=LW[/tex]

we have

[tex]L=12\ ft\\W=4\ ft[/tex]

substitute

[tex]A=(12)(4)[/tex]

[tex]A=48\ ft^2[/tex]

step 3

Find out the number of pavers needed to build the patio

Divide the area of the rectangular patio by the area of one paver

[tex]48\ ft^2/4\ ft^{2}=12\ pavers[/tex]
