How do I round 38.25 to a whole number?

1 answer:

8 0

Hi there! To round a number, you need to look at the numbers behind the decimal point. In this case, those two numbers are 2 and 5. Since 5 is in the range up rounding up (which is 5-10), we can round .25 up to .3. Now, we have 38.3. Because 3 is less than 5, we can round 38.3 down to 38.

Hope this helps!

Dmitry [639]

The area of a square is 144 cm^2. The measurement of each side is 12 cm

<u>Solution:</u>

Given, The area of a square is 144 $cm^2$

We have to find that what is the measurement of each side.

Now, we know that, area of a square = product of side value with another side value.

Let the side value of given square be "s"

Then, <em>Area of square is given as:</em>

$\begin{array}{l}{\text {area of square}=s \times s} \\\\ {\text {Area of square}=s^{2}} \\\\ {144=s^{2}} \\\\ {s=\sqrt{144}} \\\\ {s=\sqrt{12^{2}}}\end{array}$

On cancelling square root and square on right side,we get

s = 12

Hence, the side value of the square is 12 cm.
