Довжина прямокутника 8 метрів 25 сантиметрів а ширина 1/5 довжини периметра прямокутника розвязок

Answer 1

Calculation of the Rectangle's Perimeter

To find the perimeter of a rectangle, we need to know its length and width.

Given: - Length of the rectangle: 8 meters 25 centimeters - Width of the rectangle: 1/5 of the length

Let's calculate the perimeter step by step.

1. Convert the length to a single unit: - 8 meters = 800 centimeters (1 meter = 100 centimeters) - 25 centimeters

Therefore, the length of the rectangle is 825 centimeters.

2. Calculate the width: - The width is 1/5 of the length. - 1/5 of 825 centimeters = 165 centimeters.

3. Calculate the perimeter: - The perimeter of a rectangle is given by the formula: P = 2 * (length + width). - P = 2 * (825 cm + 165 cm) - P = 2 * 990 cm - P = 1980 cm.

Therefore, the perimeter of the rectangle is 1980 centimeters.
