Explanation opens after your attempt
Correct Answer
B. \(p+q\)
Concept
This is the area of \((p+q)^2\). So the side of the whole square is \(p+q\).
Why this answer is correct
The correct answer is B. \(p+q\). This is the area of \((p+q)^2\). So the side of the whole square is \(p+q\).
Exam Tip
यह \((p+q)^2\) का क्षेत्रफल है। इसलिए पूरे वर्ग की भुजा \(p+q\) होगी।
