Correct Answer

B. (20t)

Step 1

Concept

The two strips are \(5t\cdot2\) and \(5t\cdot2\), so total (20t) is subtracted. In exams, include both strips.

Step 2

Why this answer is correct

The correct answer is B. (20t). The two strips are \(5t\cdot2\) and \(5t\cdot2\), so total (20t) is subtracted. In exams, include both strips.

Step 3

Exam Tip

दो पट्टियाँ \(5t\cdot2\) और \(5t\cdot2\) हैं, इसलिए कुल (20t) घटता है। परीक्षा में दोनों पट्टियाँ शामिल करें।
