Question

Участок земли прямоугольной формы , ширина которого 0,35 км , а длина в 1,4 раза больше ,чем ширина , засеяли 41,16 ц риса . сколько килограммов риса засеяли на одном гектаре пахотной земли?( 1км2 = 100га )

Answer 1

0,35 * 1,4 = 0,49 км - длина участка
0,35 * 0,49 = 0,1715 км² = 17,15 га - площадь участка
41,16 : 17,15 = 2,4 ц = 240 кг риса засеяли на 1 га пахотной земли

Answer 2

0.35 * 1.4 = 0.49 км длина
0.35 * 0.49 = 0.1715 км ²
41.16 \ 0.1715 = 240 ц риса риса идет на 1км²

Answer 3

Calculation of Rice Seeds on One Hectare of Farmland

To calculate the amount of rice seeds sown on one hectare of farmland, we need to determine the total area of the rectangular plot and the amount of rice seeds sown.

Given: - The width of the rectangular plot is 0.35 km. - The length of the rectangular plot is 1.4 times greater than the width.

To find the length of the rectangular plot, we can multiply the width by 1.4:

Length = 0.35 km * 1.4 = 0.49 km

Next, we need to calculate the area of the rectangular plot:

Area = Length * Width

Area = 0.49 km * 0.35 km = 0.1715 km²

Since 1 km² is equal to 100 hectares, we can convert the area to hectares:

Area in hectares = 0.1715 km² * 100 = 17.15 hectares

Now, we know that 41.16 centners (or hundredweights) of rice were sown on the rectangular plot.

To find the amount of rice seeds sown on one hectare, we can use the following formula:

Amount of rice seeds per hectare = (Amount of rice seeds sown / Total area in hectares)

Amount of rice seeds per hectare = 41.16 centners / 17.15 hectares

Now, let's calculate the amount of rice seeds sown on one hectare of farmland.

Amount of rice seeds per hectare = 41.16 centners / 17.15 hectares = 2.4 centners per hectare

Therefore, 2.4 centners (or 240 kilograms) of rice seeds were sown on one hectare of paddy land.

Please note that the conversion from centners to kilograms is based on the assumption that 1 centner is equal to 100 kilograms.
