given:
Carpeting will cost $1.50 a square foot.
first floor is: L1=30ft length and W1=12ft width
sec. floor is : L2=8ft length and W2=8ft width
area:
first floor is:
A1=L1%2AW1
A1=30ft%2A12ft
A1=360ft%5E2
sec. floor is :
A2=L2%2AW2
A2=8ft%2A8ft
A2=64ft%5E2
both together:
A=A1%2BA2
A=360ft%5E2%2B64ft%5E2
A=424ft%5E2
cost:
$424%2A1.50=636
