How many square meters of tile will marco need for the walkway explain how you found your answer.

First find total area: 22 m x 26 m = 572 m^2
then find area of pool only: 16 m x 20 m = 320 m^2
subtract area of pool from total area: 572 m^2 - 320 m^2 = 252 m^2

First I found the area to the whole square, which is 572m.

Then  I found the area to the pool, which is 320m.

Lastly, I subtracted the whole square area to the pool are, which equals 252m.

The answer is, "Marco will need 252m of tile for the walkway."

I hope this helped :).
