In the following questions, two quantities are given as Quantity I and Quantity II. Find the correct relationship among them. Quantity I: Area of the square is 7200 cm2 which is four times the area of the rectangle whose length and breadth is in the ratio of 9:8. What is the sum of length and breadth of the rectangle? Quantity II: A rectangular water tank is 300 cm×488 cm is dug inside a circular field. The area of the remaining portion is 12000cm2 . Find the radius of the circular field. निम्नलिखित प्रश्नों में, दो मात्राएँ मात्रा I और मात्रा II के रूप में दी गई हैं। इन मात्राओं के बीच सही सम्बन्ध ज्ञात कीजिये। मात्रा I: एक वर्ग का क्षेत्रफल 7200 सेमी2 है जो आयत के क्षेत्रफल का चार गुना है जिसकी लम्बाई और चौड़ाई 9:8 के अनुपात में है। आयत की लंबाई और चौड़ाई का योग क्या है? मात्रा II: एक आयताकार पानी की टंकी 300 सेमी × 488 सेमी माप की एक वृत्ताकार क्षेत्र के अंदर खोदा जाता है। शेष भाग का क्षेत्रफल 12000 सेमी2 है । वृत्ताकार मैदान की त्रिज्या ज्ञात कीजिये।
