Correct Answer
A. दो (xy) आयतTwo (xy) rectangles
Concept
The mistake ignores the two cross rectangles of total area (2xy). Exam tip: never write ((x+y)2) as \(x^2+y^2\).
Why this answer is correct
The correct answer is A. दो (xy) आयत / Two (xy) rectangles. The mistake ignores the two cross rectangles of total area (2xy). Exam tip: never write ((x+y)2) as \(x^2+y^2\).
Exam Tip
गलती में दोनों क्रॉस आयतों का क्षेत्रफल (2xy) छोड़ दिया गया। परीक्षा में ((x+y)2) को कभी \(x^2+y^2\) न लिखें।
