486, (1/3) times 486 = 162, (1/3) times 162 = 54, (1/3) times 54 = 18
so answer is D
This is not much of a question, because it doesn't take into account the width of the wood trim.
So you are asked to find the perimeter of the window, ignoring the width of the trim.
P = Perimeter = 2L + 2W.
Here, P= 2(9 1/3 feet) + 2(6 3/4 feet) = 2(28/3 feet) + 2(27/4 feet)
So P = 2[28/3 + 27/4] feet. LCD is 3*4 = 12.
Thus, P = 2 [ 28/3 + 27/4 ] feet. Can you finish? Add together the fractions 28/3 and 27/4.
Answer:
20 and 13
Step-by-step explanation:
If one list is 'a' and the other one is 'b' then
a-b = 7 and a+b = 33
a-b+a+b = 7+33
2a = 40
a = 20
Now, 20 - b = 7
-b = -13
b = 13
You would have to do length times the width or count all the sides.
