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?

20 pavers

Step-by-step explanation:

step 1

Find the area of the rectangular patio

The area of a rectangle is equal to

we have

substitute

step 2

Find the area of one square paver

The area of a square is equal to

we have

---> length side of the paver

substitute

step 3

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

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
