Question

Найдите периметр прямоугольника, если одна его сторона равна 9см, а другая в 2 раза больше

Answer 1

9x2 = 18 см другая сторона прямоугольника.
9 +9 + 18 + 18 = 52 см P прямоугольника.

Answer 2

(9+9+18+18)=54............

Answer 3

Calculating the Perimeter of a Rectangle

To find the perimeter of a rectangle when one side is 9 cm and the other is 2 times larger, we can use the formula:

Perimeter (P) = 2 * (length + width)

Given that one side is 9 cm and the other is 2 times larger, we can calculate the perimeter using the following steps:

1. Identify the Length and Width: - Let's assume the length of the rectangle is 9 cm. - The width would then be 2 times the length, which is 2 * 9 = 18 cm.

2. Calculate the Perimeter: - Using the formula, we can calculate the perimeter: - P = 2 * (9 + 18) - P = 2 * 27 - P = 54 cm

Therefore, the perimeter of the rectangle is 54 cm.
