Question

Parker 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 16 feet by 8 feet. Area of a square formula A = s2. Area of a rectangle formula A = lw. How many pavers does Parker need to build the patio?

Answer 1

32.

Explanation:

I took the test.

Answer 2

32 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=16\ ft\\W=8\ ft`

substitute

`A=(16)(8)\\A=128\ 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

`128\ ft^2/4\ ft^(2)=32\ pavers`
