Question

Василиса Премудрая пошла плясать махнула левым рукавом Раскинулось в прямоугольном озеро размером 25 дм на 18 см махнула правым рукавом разлилась Квадратное озеро со стороной 15 см Какую площадь заняли оба озеро

Answer 1

S=250*18=4500см² - прямоугольное озеро
S=15*15=225см² - квадратное озеро
4500+225=4725см² - оба озера

Answer 2

Calculation of the Areas of the Two Lakes

To calculate the total area occupied by both lakes, we need to find the individual areas of each lake and then add them together.

The first lake is described as a rectangular lake with dimensions 25 dm by 18 cm. To find its area, we need to convert the dimensions to a consistent unit. Let's convert both dimensions to centimeters:

- Length: 25 dm = 250 cm (since 1 dm = 10 cm) - Width: 18 cm

Now we can calculate the area of the first lake:

Area of the first lake = Length × Width = 250 cm × 18 cm = 4500 cm² [[1]].

The second lake is described as a square lake with a side length of 15 cm. The area of a square is calculated by squaring the length of one of its sides. Therefore, the area of the second lake is:

Area of the second lake = Side length × Side length = 15 cm × 15 cm = 225 cm² [[2]].

To find the total area occupied by both lakes, we simply add the areas of the two lakes together:

Total area occupied by both lakes = Area of the first lake + Area of the second lake = 4500 cm² + 225 cm² = 4725 cm².

Therefore, the total area occupied by both lakes is 4725 cm².

Please note that the calculations assume that the lakes are completely filled and have no irregularities or variations in depth.
