एक (a+b) वर्ग को चार भागों में काटकर आयत में बदला गया। यदि आयत की एक भुजा (a+b) ही रहती है, तो दूसरी भुजा क्या रहेगी?

Correct Answer
B. (a+b)
Concept
Area is unchanged and one side is unchanged, so the other side is also (a+b). In exams, infer using equal area and equal side.
Why this answer is correct
The correct answer is B. (a+b). Area is unchanged and one side is unchanged, so the other side is also (a+b). In exams, infer using equal area and equal side.
Exam Tip
क्षेत्रफल समान और एक भुजा समान है, इसलिए दूसरी भुजा भी (a+b) होगी। परीक्षा में समान क्षेत्रफल और समान भुजा से निष्कर्ष निकालें।
