Answer 1

1 фигура) 6×26=156см²
2 фигура) 1дм 4 см×3 дм=14см×30см=420см=42дм
3 фигура) 2дм 5см×3дм=25см×30см=750см=75дм

Answer 2

Calculating the Areas of the Figures

To find the areas of the given figures, we can use the following measurements:

1. 6 cm and 26 cm 2. 1 dm 4 cm and 3 dm 3. 2 dm 5 cm and 3 dm

Let's calculate the areas for each figure.

1. For the first figure with sides of 6 cm and 26 cm: - The area can be calculated using the formula for the area of a rectangle: *Area = length × width*. - Substituting the given values, the area is: *Area = 6 cm × 26 cm*. - This gives us an area of 156 square centimeters.

2. For the second figure with sides of 1 dm 4 cm and 3 dm: - To calculate the area, we first need to convert the measurements to the same unit. 1 dm is equal to 10 cm. - So, the sides become 14 cm and 30 cm. - Using the formula for the area of a rectangle: *Area = length × width*, we get: *Area = 14 cm × 30 cm*. - This gives us an area of 420 square centimeters.

3. For the third figure with sides of 2 dm 5 cm and 3 dm: - Converting the measurements to the same unit, we get sides of 25 cm and 30 cm. - Using the formula for the area of a rectangle: *Area = length × width*, we get: *Area = 25 cm × 30 cm*. - This gives us an area of 750 square centimeters.

So, the areas of the given figures are: 1. 156 square centimeters 2. 420 square centimeters 3. 750 square centimeters
