Антон и Ксюша в связи с расширением производства запланировали арендовать
новое помещение для своей компании. Проведя предварительный анализ базы
данных сдаваемых в аренду помещений, они выбрали из них два наиболее инте-
ресных. План первого помещения был выполнен в масштабе 1: 500. Измерения
показали, что на плане площадь арендуемого помещения прямоугольной формы
равна 42 см2. План второго помещения был выполнен в масштабе 1: 200, а его
площадь на плане – 250 см2. Ставка арендной платы за первое помещение соста-
вила 1000 р. в год за 1 м2, а за второе 1200 р. в год за 1 м2. За какое из этих
помещений ежемесячная арендная плата получилась меньшей?
