If $$\sqrt{108} + \sqrt{243} = 25.98$$. find the value of $$\sqrt{147} + \sqrt{192}$$.​

Correct option is A

Given: 

$$\sqrt{108} + \sqrt{243} = 25.98 \\\ \\6\sqrt{3} + 9\sqrt{3} = 25.98\\\ \\15\sqrt{3} = 25.98\\\ \\\sqrt{3} = 1.732$$

Solution:

$$\sqrt{147} + \sqrt{192}$$.

= $$\sqrt{7\times 7 \times 3 } + \sqrt{64 \times 3}$$ 

= $$7\sqrt{3} + 8\sqrt{3}$$ 

= $$15 \sqrt{3}$$ 

= $$15 \times 1.732$$ 

= 25.98
