Answer:
(a)Area of the bedroom=96 square inches
(b)Area of the living room =144 square inches
(c)Area of the dollhouse that is not of the bedroom or living room =336 square inches.
Step-by-step explanation:
The area of the bedroom is 1/6 the area of the entire dollhouse
The area of the living room is 3/2 times the area of the bedroom.
The area of the entire dollhouse is 576 square inches
Let the area of bedroom=b
Let the area of living room=l
(a) The area of the bedroom is 1/6 the area of the entire dollhouse
square inches
(b)The area, in square inches, of the living room
The area of the living room is 3/2 times the area of the bedroom
l= square inches
(c)The total area of the house =576 square inches
Area of the bedroom=96 square inches
Area of the living room =144 square inches
Area of the dollhouse that is not of the bedroom or living room
=576-(96+144)=576-240=336 square inches.
The area of the living room is 3/2 times the area of the bedroom
This is gotten by subtracting the area of the bedroom and living room from the total area of the house.
