Answer 1

Answer:

Step-by-step explanation:

Per meter cost of carpet = 80;

Total cost = 19200;

Carpet width = 75cm = 0.75m;

Length of room = 15 m;

Total cost = 19200 = Total Length of carpet * Per meter cost of carpet;

19200 = $\frac{15}{0.75}$ * width * 80;

19200 = width* 1600;

Width of the room = $\frac{19200}{1600}$

=16 m

Answer 2

Answer:

width of the room = 16 metre
