Correct Answer

B. (10x)two rectangular strips

Step 1

Concept

Two (5x) strips were missed, so total (10x) was missed. In exams do not treat ((a+b)2) as \(a^2+b^2\).

Step 2

Why this answer is correct

The correct answer is B. (10x) / two rectangular strips. Two (5x) strips were missed, so total (10x) was missed. In exams do not treat ((a+b)2) as \(a^2+b^2\).

Step 3

Exam Tip

दो (5x) पट्टियां छूटी हैं इसलिए कुल (10x) छूटा। परीक्षा में ((a+b)2) को \(a^2+b^2\) न समझें।
