### Bennette's Square Root Scribe Post

QUESTION:
12. While shopping online, Ji Hun finds a square rug with an area of 11 m2. He needs to know if it will fit in his 4 m × 5 m bedroom.

a) Estimate the side length of the rug, to one decimal place.
b) Check your estimate with a calculator.
c) Will the rug fit? Explain.

a.) 3 x 3 = 9
4 x 4 = 16

9 is closer to 11. But in this question, they're looking for side length.
Since the side length of 9 is 3, we'll use 3 for our whole number.
3. ___

 From Drop Box

Now, we just need to find out one decimal to replace the blank. To find the answer to that, count the intervals between 9 and 11.
11 - 9 = 2

The estimated answer will be, 3.2 m

b.)
By using my calculator, I multiplied 3.2 by itself to check it.
3.2 x 3.2 = 10.24

To find the whole number and one decimal place, use your calculator and find the square root of 11.

 From Drop Box

c.)
Yes, the rug will fit because the sides of the rug is smaller than the size of his room.
