यदि एक वर्ग के क्षेत्र मॉडल में \(x^2\), \(5x\), \(5x\) और \(25\) भाग हैं तो पूरा क्षेत्रफल क्या है?
If a square area model has parts \(x^2\), \(5x\), \(5x\), and \(25\), what is the whole area?
Explanation opens after your attempt
B. \(x^2+10x+25\)
Concept
The two \(5x\) parts combine to form \(10x\). So the total is \(x^2+10x+25\).
Why this answer is correct
The correct answer is B. \(x^2+10x+25\). The two \(5x\) parts combine to form \(10x\). So the total is \(x^2+10x+25\).
Exam Tip
दोनों \(5x\) भाग मिलकर \(10x\) बनाते हैं। इसलिए कुल \(x^2+10x+25\) है।
