Surface area of a rectangular carpet is Length×width
now [5×2.2] yard =11 yard now it's cost will be 11×12$=132$
Now total surface area of the room excluding the carpet 7 (4.5+1.5) yard= 52 yard Now the total cost will be 52×12$=624$
Now total surface area of the room including the carpet is
(624+132)$=756$.
Answer:
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 $
