D. \(p^2+10p+25\)
Concept
In ((p+5)2), there are two (5p) rectangles and a small square (25). So the area is \(p^2+10p+25\).
Why this answer is correct
The correct answer is D. \(p^2+10p+25\). In ((p+5)2), there are two (5p) rectangles and a small square (25). So the area is \(p^2+10p+25\).
Exam Tip
((p+5)2) में दो (5p) आयत और (25) छोटा वर्ग होता है। इसलिए क्षेत्रफल \(p^2+10p+25\) है।
