If this is a maths problem then:
The room is 12'4" by 13'4" ~= 144.44 sq ft
~= 144.44 ÷ 9 sq yd
~= 18.27 square yards
At 23.25 per sq yd this costs:
cost ~= 23.25 * 18.27
~= 424.81
If this is a real world question then:
Carpet normally comes in rolls 4m (13'2") wide from which a whole width strip is purchased. The 13'4" dimension is longer than this, so the 12'4" dimension will come from the width and the 13'4" dimension will be the required length of strip. However, a little excess is allowed for fitting and so a strip 13'6" long will probably be needed to be purchased. (The 10" excess on the width will be wastage.)
Thus the required carpet is about 13'2" x 13'6" = 19.75 sq yds
This will cost 19.75 x 23.25 ~= 459.19
There will also be underlay, carpet gripper and door bars to be factored into the cost.
Some carpets do come in 5m (16'5") wide rolls, but if allowing this for the wider dimension, it would require about 16'5" x 12'6" ~= 22.8 sq yds giving more wastage and cost.
