PLEASE HELP ANSWER FAST!! Ms. Finch is getting new carpet installed in her living room and hallway. The carpet will not be on the stairs. The cost of installation is $12 per square yard. What is the total area and cost of where the carpet is being installed?

45yd^2

540$

Step-by-step explanation:

The surface will be : total area- the area of the stairs

total area=(4.5+2+1.5)*7=8*7=56 yd^2

area of the stairs=2*5.5=11 yd^2

area of the carpet will be  56-11=45yd^2

total cost =45*12=540 $

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

$12. that is my answer.
