Birinchi yo'lkaning yuzi quyidagicha hisoblanadi: 17 m 40 sm (17,4 m) * 1 m 48 sm (1,48 m) = 25,792 m². Ikkinchi yo'lka uchun esa: 15 m 80 sm (15,8 m) * 1 m 12 sm (1,12 m) = 17,696 m². Demak, dastlabki yo'lka kattaroq va u 25,792 m² - 17,696 m² = 8,096 m² katta. Shunday qilib, birinchi yo'lkaning yuzi ikkinchisidan 8,096 m² ga katta. O'yingizda shuni malumki, yuza ko'paytmalari orqali hisoblash juda oddiy va har qanday o'lchov birligini konvertatsiya qilish orqali osonlikcha amalga oshirilishi mumkin. Bu hisob-kitobni osonlashtiradi va qanday qiyinchilik boshdan kechirasiz degan savolni tug'dirmaydi!
