Correct Answer

B. (16)

Step 1

Concept

Area is (\(\sqrt{18}\)2-\(\sqrt{2}\)2=18-2=16). Conjugate dimensions can give rational area.

Step 2

Why this answer is correct

The correct answer is B. (16). Area is (\(\sqrt{18}\)2-\(\sqrt{2}\)2=18-2=16). Conjugate dimensions can give rational area.

Step 3

Exam Tip

क्षेत्रफल (\(\sqrt{18}\)2-\(\sqrt{2}\)2=18-2=16) है। संयुग्मी आयाम परिमेय क्षेत्रफल दे सकते हैं।
