анонимВыразим в квадратных метрах и квадратных дециметрах.
Так как, в 1 м^2 = 10 дм^2 и в 1 м^2 = 100 см^2, тогда получим:
1) 3,15 м^2 = 3,15 * 1 м^2 = 3,15 * 10 дм^2 = 31,5 дм^2;
3,15 * м^2 = 3,15 * 1 м^2 = 3,15 * 100 см^2 = 315 см^2;
Значит, 3,15 м^2 = 31,5 дм^2 = 315 см^2.
2) 4,08 м^2 = 4,08 * 1 м^2 = 4,08 * 10 дм^2 = 40,8 дм^2;
4,08 м^2 = 4,08 * 1 м^2 = 4,08 * 100 см^2 = 408 см^2.
Значит, 4,08 м^2 = 40,8 дм^2 = 4,08 см^2.
