Answer:
$420
Step-by-step explanation:
In the figure, the living room is 5 cm by 3.5 cm.
We use the scale to convert to the real measurements.
1 cm = 4 ft
5 cm * 4 ft/cm = 20 ft
3.5 cm * 4 ft/cm = 14 ft
The actual dimensions of the room are 20 ft by 14 ft.
actual area = 20 ft * 14 ft = 280 ft²
carpet cost = $1.50/ft²
cost of carpet = 280 ft² * $1.50/ft²
cost of carpet = $420
