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

12 pavers

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`
