Question

Allison is laying pavers to build a patio in her backyard. Each square paver measures 2 feet on each side. She would like the patio to be 12 feet by 4 feet.
Area of a square formula A = s2.
Area of a rectangle formula A = lw.

How many pavers does Allison need to build the patio?

Answer 1

Answer:

12 pavers

Step-by-step explanation:

step 1

Find out the area of one square paver

The area of a square is

$A=s^{2}$

where

s is the length side of the square

we have

$s=2\ ft$

substitute

$A=2^{2}$

$A=4\ ft^{2}$

step 2

Find out the area of the rectangular patio

we know that

The area of a rectangle is

$A=LW$

we have

$L=12\ ft\\W=4\ ft$

substitute

$A=(12)(4)$

$A=48\ ft^2$

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

$48\ ft^2/4\ ft^{2}=12\ pavers$
