We are given that the shape of the room is a square .
So formula for area of a square is given by:
Area = side * side = side²
Now in the question we are given that the area of the square room is 128 square feet and we have to estimate the side of this square.
So plugging the value of area in the formula given above to find the side,
128 = side²
taking square root on both sides
side = 11.3137 feet
Answer : The best estimate of one side of the room is 11.3137 feet.

35×10=5×7×2×5
25×14=350
20,000 * .05 = 1,000 1,000 * 3 = 3,000 20,000 + 3,000 = 23,000 Hope This helps :)
Answer:
Step-by-step explanation:
1) First, we figure out the number of blue and green marbles (27 each)
2) Subtract the 6 blue and 3 green marbles. We now have 21 blue marbles and 24 green marbles.
3) Since we want to have more blue marbles while taking out the <em>minimum</em> number of green, we're going to take out green marbles out until there's one less than blue. Because there's 21 blue, we want 20 green. We've taken out 4/13 marbles so far.
4) Now, we're going to take 1 marble out of both the greens and blues until we have 17 blue and 16 green. We've now taken out 12/13 marbles. We can't make the 13th marble a blue one, otherwise we even them out, so we'll take another green. Now we have 17 blue and 15 green.
5) Count the number of greens you've taken out, and voila!
