Answer:
It will cost $19.25 to place the baseboard around the region
Explanation:
The total number of feet that need the baseboard is the perimeter of the region minus 2 ft for the door.
10 ft + 7 ft + (13 - 2) ft + 3 ft + 4 ft = 35 ft
Now the cost is $0.55 per foot; therefore, for 35 ft the cost will be
[tex]cost\text{ per foot }\times number\text{ of feet}=\frac{\$0.55}{ft}\times35ft=\$19.25[/tex]Hence, the cost to place baseboard around the region will be $19.25.
