It is given that a is equal to b square if a is equal to 20 ±0.01 then...
Understanding the Relationship Between a and b
Given that \( a = b^2 \), we can derive the value of \( b \) from the provided information about \( a \).

Given Values:
- \( a = 20 \pm 0.01 \)
To find \( b \), we need to solve for \( b \):
\[
b = \sqrt{a}
\]

Calculating the Central Value of b:
- Substituting \( a \):
\[
b = \sqrt{20} \approx 4.47
\]

Calculating the Uncertainty in b:
To find the uncertainty in \( b \), we use the formula for propagation of uncertainty:
\[
\Delta b = \frac{1}{2\sqrt{a}} \cdot \Delta a
\]
Where:
- \( \Delta a = 0.01 \)
Substituting the values:
\[
\Delta b = \frac{1}{2\sqrt{20}} \cdot 0.01 \approx \frac{1}{2 \cdot 4.47} \cdot 0.01 \approx 0.00112
\]
Rounding off gives us:
\[
\Delta b \approx 0.01
\]

Final Value of b:
Thus, the value of \( b \) can be expressed as:
\[
b \approx 4.47 \pm 0.01
\]

Conclusion:
In summary, when \( a \) is \( 20 \pm 0.01 \), we find:
- \( b \) is approximately \( 4.47 \pm 0.01 \) cm.
This demonstrates how to effectively use the relationship between two variables and the propagation of uncertainties to arrive at a final value.
