Question

2. Решите задачу Родители постоянно воспитывали Свету и заставляли ее делать домашку по математике. Света не выдержала и сбежала от них на маленький необитаемый остров прямоугольной формы. Найдите площадь острова, если известно, что он прямоугольной формы, его длина 240 км, а ширина в 2 раза больше.

Answer 1

Ответ:

240 х 2=480

480 х 240=115200

Answer 2

Ответ:67.200 км2

Пошаговое объяснение:

1)240*2=480(км)-ширина

2)240*480=67.200(км2)-площадь острова

Answer 3

Problem Analysis

To find the area of the rectangular island, we need to know its length and width. The problem states that the length of the island is 240 km, and the width is twice the length. We can use this information to calculate the area of the island.

Calculation

Let's calculate the width of the island first. Since the width is twice the length, we can multiply the length by 2:

Width = 240 km * 2 = 480 km

Now that we have the length and width of the island, we can calculate its area by multiplying the length and width:

Area = Length * Width = 240 km * 480 km

To calculate the area, we need to multiply the length and width. Let's perform the calculation:

Area = 115,200 km²

Therefore, the area of the rectangular island is 115,200 square kilometers.

Conclusion

The area of the rectangular island, given that its length is 240 km and its width is twice the length, is 115,200 square kilometers.
