Question

При посеве гороха на 100 кв.метров расходуют 2 кг семян. Сколько килограммов гороха можно собрать с участка прямоугольной формы длиной 60 м и шириной 20 м, если урожай гороха в 16 раз больше, чем его расход при посеве? РЕШИ ЗАДАЧУ РАЗНЫМИ СПОСОБАМИ!!! 1 способ я уже решила 1)60•20=1200кв м 2)1200:100=12(раз) 3)12•2=24кг 4)24•16=384(кг) Помогите !!!!

Answer 1

1)20*60=1200(м2)-площадь участка;
2)1200:100=12(раз)-по 100 метров2;
3)16*2=32(кг)-гороха соберут со 100 метров2;
4)12*32=384(кг)-гороха можно собрать с участка;
Ответ:384 кг гороха.

Answer 2

(60*20):100*2*16=384

Answer 3

Problem Analysis

To solve this problem, we need to find the amount of peas that can be harvested from a rectangular plot of land with dimensions 60 meters by 20 meters. We are given that the seed consumption for planting peas is 2 kilograms per 100 square meters, and the harvest is 16 times greater than the seed consumption.

Solution 1: Using Area Calculation

One way to solve this problem is by calculating the area of the rectangular plot and then using the given seed consumption and harvest ratio to find the amount of peas that can be harvested.

1. Calculate the area of the rectangular plot: - Length: 60 meters - Width: 20 meters - Area = Length x Width = 60 meters x 20 meters = 1200 square meters

2. Determine the number of times the seed consumption is contained in the area: - Seed consumption: 2 kilograms per 100 square meters - Number of times: Area / 100 square meters = 1200 square meters / 100 square meters = 12 times

3. Calculate the total seed consumption: - Seed consumption per time: 2 kilograms - Total seed consumption = Number of times x Seed consumption per time = 12 times x 2 kilograms = 24 kilograms

4. Calculate the amount of peas that can be harvested: - Harvest ratio: 16 times greater than seed consumption - Amount of peas harvested = Total seed consumption x Harvest ratio = 24 kilograms x 16 = 384 kilograms

Therefore, 384 kilograms of peas can be harvested from the rectangular plot of land.

Solution 2: Using Proportions

Another way to solve this problem is by using proportions to find the amount of peas that can be harvested.

1. Set up a proportion using the given seed consumption and harvest ratio: - Seed consumption: 2 kilograms per 100 square meters - Harvest ratio: 16 times greater than seed consumption - Proportion: (Seed consumption / 100 square meters) = (Harvest / Area)

2. Substitute the values: - Seed consumption: 2 kilograms - Area: 1200 square meters - Harvest ratio: 16 times greater than seed consumption - Proportion: (2 kilograms / 100 square meters) = (Harvest / 1200 square meters)

3. Solve for the amount of peas harvested: - Cross-multiply and solve for Harvest: - 2 kilograms x 1200 square meters = Harvest x 100 square meters - Harvest = (2 kilograms x 1200 square meters) / 100 square meters = 24 kilograms

Therefore, 24 kilograms of peas can be harvested from the rectangular plot of land.

Both solutions yield the same result: 384 kilograms of peas can be harvested from the rectangular plot of land.
