A.
Area of the pool is 320 m²
Area of the pool and walkway is 572 m²
B. The square meters of tile Marco will need for the walk way is 252 m²
What is the area of the pool?
Area of the pool = Length × Width
= 20 m × 16 m
= 320 m²
Area of the pool and walkway = Length × Width
= 26 m × 22 m
= 572 m²
Area of the walkway = Area of the pool and walkway - Area of the pool
= 572 m² - 320 m²
= 252 m²
Hence, the square meters of tile Marco needs for the walkway is equivalent to the area of the walkway, which is 252 m².
