Correct Answerसही उत्तर
C. 469 cm²C. 469 सेमी²
Explanationव्याख्या
Rectangle area = 28 × 14 = 392 cm².
Semicircle radius = 7 cm, so its area = 1
2 × 22
7 × 7² = 77 cm².
Total area = 392 + 77 = 469 cm².
आयत का क्षेत्रफल = 28 × 14 = 392 सेमी²।
अर्धवृत्त की त्रिज्या = 7 सेमी और क्षेत्रफल = 77 सेमी²।
कुल क्षेत्रफल = 392 + 77 = 469 सेमी²। ---
