Question

Marcus is laying pavers to build a patio in his backyard. Each square paver measures 2 feet on each side. He would like the patio to be 20 feet by 4 feet.

Area of a square formula A = s2.
Area of a rectangle formula A = lw.

How many pavers does Marcus need to build the patio?

Answer 1

20 pavers

Explanation:

step 1

Find the area of the rectangular patio

The area of a rectangle is equal to

`A=LW`

we have

`L=20\ ft\\W=4\ ft`

substitute

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

step 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

`80/4=20\ pavers`
