| **A rectangular plot of land, 30 meters long and 10 meters wide, was sown with beets. How many grams of beet seeds were used for sowing if 13 grams of seeds are needed for every 10 square meters of land?**

Let’s calculate the area of the sown plot of land. Since the site is rectangular, its area is equal to the product of length and width:

30 * 10 = 300 (m²).

A plot of 300 m² is 30 times larger than a plot of 10 m², therefore, to plant it, you need 30 times more seeds than a plot of 10 m².

Therefore, to sow a rectangular plot of land 30 meters long and 10 meters wide, the following mass of beet seeds is required:

13 * 30 = 390 (g).

Answer: 390 g of seeds.
