Per NCERT, applying Brahmagupta's formula to a RECTANGLE of sides a, b (which is cyclic), what value emerges for the area — confirming the result we already know?
Aab (the standard rectangle area)
Ba² + b²
Ca + b
D½ab
Answer & Solution
Correct answer: A. ab (the standard rectangle area)
Per NCERT's Example 6, Brahmagupta's formula simplifies to √(ab × ab) = ab for a rectangle — verifying the known result.
