Step-by-step explanation:

step 1

Find the area of the rectangular patio

$L=20\ ft\\W=4\ ft$

substitute

$A=(20)(4)=80\ ft^2$

Find the area of one square paver

The area of a square is equal to

$A=s^2$

we have

$s=2\ ft$ ---> length side of the paver

substitute

$A=2^2=4\ ft^2$

step 3

Divide the area of the rectangular patio by the area of one paver to find out the number of pavers needed
