Answer:

45.6 ft

Step-by-step explanation:

The room is a rectangle. The perimeter of a rectangle is

perimeter = 2L + 2W

perimeter = 2(12.62 ft) + 2(10.2 ft)

perimeter = 25.24 ft + 20.4 ft

perimeter = 45.64 ft

Since 10.2 ft has only 3 significant digits, the answer must also have only 3 significant digits.

Answer: perimeter = 45.6 ft

Answer:

-49

Step-by-step explanation:

it would be this because first we would have to figure out what 6*10 is that why we know what to distribute . so once we figure it out , which is 70 . We would then subtract 14 from 70 . Since 7 is right next to 2 we would then multiply it to get to 14. Once we get that you should get 56, from there you would subtract 56 to 105 , and get your answer.
