The question I was given:
To solve: First, I multiplied 8.2m by 4.5m and I got 36.90 or 36.9
Then I multiplied 36.9 by 2/5. But before I multiplied both numbers, I converted 2/5 into decimals to make it easier.
After, I multiplied 36.9 by 0.4 and I got 14.76
Lastly, I found the square root of 14.76 which equals to 3.8
S.S. The side lengths of the rug is 3.8m
