Let the equation of ellipse be `x^(2)/(a^(2)+1)=y^(2)/(a^(2)+2)=1` Statement 1 If eccentricity of the ellipse be `1/sqrt6`, then length of latusrectum is `10/sqrt6`. Statement 2 Length of latusrectum=`(2(a^(2)+1))/(sqrt(a^(2)+2))`

Answer

To solve the problem step by step, we will analyze the given ellipse equation and verify the statements provided.

### Step 1: Identify the standard form of the ellipse
The given equation of the ellipse is:
\[ \frac{x^2}{a^2 + 1} = \frac{y^2}{a^2 + 2} = 1 \]
This can be rewritten in the standard form of an ellipse:
\[ \frac{x^2}{b^2} + \frac{y^2}{a^2} = 1 \]
where \( b^2 = a^2 + 1 \) and \( a^2 = a^2 + 2 \).

### Step 2: Compare and find \(a^2\) and \(b^2\)
From the comparison, we have:
- \( b^2 = a^2 + 1 \)
- \( a^2 = a^2 + 2 \)

This indicates that we need to correct our interpretation. The correct comparison should yield:
- \( a^2 = a^2 + 2 \) (which is incorrect)
- \( b^2 = a^2 + 1 \)

Instead, we should have:
\[ b^2 = a^2 + 1 \quad \text{and} \quad a^2 = a^2 + 2 \implies \text{(not valid)} \]
Thus, we will consider the correct interpretation of the ellipse parameters.

### Step 3: Calculate the eccentricity
The eccentricity \( e \) of an ellipse is given by:
\[ e = \sqrt{1 - \frac{b^2}{a^2}} \]
From the earlier equations, we have:
\[ b^2 = a^2 + 1 \quad \text{and} \quad a^2 = a^2 + 2 \]
This leads to:
\[ e^2 = 1 - \frac{a^2 + 1}{a^2} \]
Substituting \( e = \frac{1}{\sqrt{6}} \):
\[ \left(\frac{1}{\sqrt{6}}\right)^2 = 1 - \frac{a^2 + 1}{a^2} \]
This simplifies to:
\[ \frac{1}{6} = 1 - \left(1 + \frac{1}{a^2}\right) \]
Solving this gives:
\[ \frac{1}{6} = -\frac{1}{a^2} \]
Thus,
\[ a^2 = 6 \]

### Step 4: Find \(b^2\)
Now substituting \( a^2 = 6 \) into the equation for \( b^2 \):
\[ b^2 = a^2 + 1 = 6 + 1 = 7 \]

### Step 5: Calculate the length of the latus rectum
The length of the latus rectum \( L \) is given by:
\[ L = \frac{2b^2}{a} \]
Substituting \( b^2 = 7 \) and \( a = \sqrt{6} \):
\[ L = \frac{2 \times 7}{\sqrt{6}} = \frac{14}{\sqrt{6}} = \frac{14\sqrt{6}}{6} = \frac{7\sqrt{6}}{3} \]

### Step 6: Verify the length of the latus rectum
The statement claims that the length of the latus rectum is \( \frac{10}{\sqrt{6}} \). To verify:
\[ \frac{10}{\sqrt{6}} \neq \frac{7\sqrt{6}}{3} \]
Thus, Statement 1 is false.

### Conclusion
- **Statement 1**: False
- **Statement 2**: True (as derived earlier)
