Question

Длина прямо угольник 65 см ширина 1 дм 7 см Найди периметр и площадь прямо угольника

Answer 1

Периметр: (65см+1 дм 7см)*2=(65см+17см)*2=82см*2=164 см
площадь: 65см * 1дм 7 см=65см*17см=1105 см2=11 дм2 5см2

Answer 2

Площадь. 65*17=1105

Периметр. 65+65+17+17=164 вот как то так

Answer 3

Perimeter and Area of a Rectangle

To find the perimeter and area of a rectangle, we need to know its length and width. In this case, the length of the rectangle is 65 cm and the width is 1 dm 7 cm.

Perimeter of a Rectangle

The perimeter of a rectangle is the sum of all its sides. For a rectangle with sides of length a, b, c, and d, the perimeter (P) can be calculated using the formula:

P = a + b + c + d In this case, the length of the rectangle is 65 cm and the width is 1 dm 7 cm. To calculate the perimeter, we need to convert the width to centimeters. Since 1 decimeter (dm) is equal to 10 centimeters (cm), the width can be expressed as 17 cm. Therefore, the perimeter of the rectangle is:

P = 65 cm + 17 cm + 65 cm + 17 cm = 164 cm So, the perimeter of the rectangle is 164 cm.

Area of a Rectangle

The area of a rectangle is the product of its length and width. For a rectangle with length a and width b, the area (A) can be calculated using the formula:

A = a * b In this case, the length of the rectangle is 65 cm and the width is 1 dm 7 cm (or 17 cm). Therefore, the area of the rectangle is:

A = 65 cm * 17 cm = 1105 cm^2 So, the area of the rectangle is 1105 square centimeters (cm^2).

To summarize: - Perimeter of the rectangle: 164 cm - Area of the rectangle: 1105 cm^2
