Question

лес имеет прямоугольную форму.два велосипедиста выехали и одного угла лес и поехали по его краям до сеседних углов леса.оба доехали за 5 минут.один ехал со скоростью 120м/мин-другой 200м/мин.найди площадь леса.(ВЫ БУДИТЕ ДЕЛАТЬ ИЛИ НЕТ!!!!!!!)

Answer 1

1)120 * 5 = 600(м) - ширина прямоугольника

2)200 * 5 = 1000(м) - длина прямоугольника

3)1000 * 600 = 600000(м2)

Ответ: площадь леса 600000м2.

Answer 2

Calculation of the Area of the Forest

To calculate the area of the forest, we need to determine the dimensions of the rectangular shape. Let's assume that the length of the forest is represented by the longer side of the rectangle, and the width is represented by the shorter side.

We are given that two cyclists started at one corner of the forest and rode along its edges until they reached the adjacent corners. Both cyclists completed this journey in 5 minutes. One cyclist traveled at a speed of 120 m/min, while the other cyclist traveled at a speed of 200 m/min.

Let's denote the length of the forest as L and the width as W.

Calculation Steps

1. We can calculate the time it took for each cyclist to travel along the length of the forest using the formula: time = distance / speed. - For the cyclist traveling at 120 m/min: L / 120 = 5 minutes. - For the cyclist traveling at 200 m/min: L / 200 = 5 minutes.

2. Solving these equations will give us the value of L.

3. We can calculate the time it took for each cyclist to travel along the width of the forest using the formula: time = distance / speed. - For the cyclist traveling at 120 m/min: W / 120 = 5 minutes. - For the cyclist traveling at 200 m/min: W / 200 = 5 minutes.

4. Solving these equations will give us the value of W.

5. Finally, we can calculate the area of the forest using the formula: area = length * width.

Let's perform the calculations:

1. For the cyclist traveling at 120 m/min: - L / 120 = 5 minutes. Solving for L: L = 120 * 5 = 600 meters.

2. For the cyclist traveling at 200 m/min: - L / 200 = 5 minutes. Solving for L: L = 200 * 5 = 1000 meters.

3. For the cyclist traveling at 120 m/min: - W / 120 = 5 minutes. Solving for W: W = 120 * 5 = 600 meters.

4. For the cyclist traveling at 200 m/min: - W / 200 = 5 minutes. Solving for W: W = 200 * 5 = 1000 meters.

5. Calculating the area of the forest: - Area = Length * Width. - For the dimensions L = 1000 meters and W = 600 meters, the area of the forest is 1000 * 600 = 600,000 square meters.

Therefore, the area of the forest is 600,000 square meters.
