Step-by-step explanation:
Perimeter of swimming pool = 2(l + w)
2(24 + 12)
2(36)
72
Perimeter of walkway = 2(l + w)
2(4c + 4w) [ Since it is saying all side]
8c + 8w
Expression = 72 + 8c + 8w
Answer:
the perimeter of the pool WITHOUT the walkaway and the wooden deck would be:
P=(2*24)+(2*12)=72
we add the concrete walkway
72+8c
we add the wooden deck
72+8c+8w
