A floor of a room is in the shape of square. It is to be covered with rectangular tiles that each have an area of 192 square inc
Grace [21]
Find area of room
aera=legnth wtimes width
in a square, legnth=width
aera=legnth^2
legnth=14 feet
convert o inches
14*12=168 inches
area=168^2=28224 square inches

how many tiles will cover all of floor?
aka
how many 192 in^2 is at least 28224 (at least, because we need to cover the whole floor without gaps)
192x<u>></u>28224
divide both sides by 192
x<u>></u>147

147 is the number of tiles we need

What is the answer to this Question
mixer [17]
15. n - 6 = 21......add 6 to both sides
    n = 21 + 6
    n = 27

16. p + 1 3/4 = 4 5/8...turn mixed numbers to improper fractions
     p + 7/4 = 37/8....there is 2 ways to continue from here...I will show u            both

(1) p + 7/4 = 37/8....multiply everything by common denominator of 8, this gets rid of the fractions.
8p + 14 = 37 (result of multiplying by 8)
8p = 37 - 14
8p = 23
p = 23/8

(2) p + 7/4 = 37/8...subtract 7/4 from both sides
      p = 37/8 - 7/4...common denominator is 8
      p = 37/8 - 14/8
      p = 23/8

either way u use, u will arrive at the same answer
