A.
Lets find the total area of the rectangular building

A(building)=l*w    where l=length and w=width
A(building)=22*26
A(building)=572m²

Answer=572m²

B. 
Now lets find the area of the pool

A(pool)=l*w     where l=length and w=width
A(pool)=16*20
A(pool)=320m²

To find out the area of the walkway. Subtract the area of the pool from the area of the building

A(building)-A(pool)=A(walkway)
572m²-320m²=252m²
A(walkway)=252m²

Answer= 252m²
