I got $600, but the answer is $200?

Answer 1

Answer:

$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.

Explanation:

Length of the room = l = 15.0 ft = $\frac{15.0}{3} yard=5.0 yard$

Width of the room = w = 12.0 ft = $\frac{12.0}{3} yard=4.0 yard$

(1 yard = 3 feet)

Area of the room = l × w = $4.0 yard\times 5.0 yard = 20.0 yard^2$

Cost for installing a carpet for a room = $10 per square yard

Cost for installing a carpet for a room wit area 20.0 square yard :

$20.0 yard^2\times 10/ yard^2= 200.0$

$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.
