599. 201 м 30 см - 56 м 47 см

To solve this problem, we need to subtract the lengths given. First, we subtract the centimeters: 30 cm - 47 cm. Since we cannot subtract 47 from 30, we borrow 1 meter (which is 100 cm) from 201 m. Now we have 201 m - 1 m = 200 m, and 30 cm + 100 cm = 130 cm. Then, we subtract the centimeters: 130 cm - 47 cm = 83 cm. Next, we subtract the meters: 200 m - 56 m = 144 m. The total length is 144 m and 83 cm.
