एक (5t-2) भुजा वाले वर्ग में घटाई गई दो पट्टियों का कुल क्षेत्रफल कितना है?
In a square of side (5t-2), what is the total area of the two subtracted strips?
Explanation opens after your attempt
B. (20t)
Concept
The two strips are \(5t\cdot2\) and \(5t\cdot2\), so total (20t) is subtracted. In exams, include both strips.
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.
Exam Tip
दो पट्टियाँ \(5t\cdot2\) और \(5t\cdot2\) हैं, इसलिए कुल (20t) घटता है। परीक्षा में दोनों पट्टियाँ शामिल करें।
