Can we construct any triangle of side lengths 2 m, 3 m and 6 m?

Question : The ratio of the length of each equal side and the third side of an isosceles triangle is 3 : 5. If the area of the triangle is $30 \sqrt{11}$ cm², then the length of the third side (in cm) is:

Option 1: $10\sqrt{6}$

Option 2: $5\sqrt{6}$

Option 3: $13\sqrt{6}$

Option 4: $11\sqrt{6}$

Question : The longest side of the obtuse triangle is 7 cm and the other two sides of the triangle are 4 cm and 5 cm. Find the area of the triangle.

Option 1: $1 \sqrt{3} \mathrm{~cm}^2$

Option 2: $6 \sqrt{3} \mathrm{~cm}^2$

Option 3: $3 \sqrt{2} \mathrm{~cm}^2$

Option 4: $4 \sqrt{6} \mathrm{~cm}^2$
