Answer 1

1) 18 : 9 = 2 (см) -ширина прямоугольника .
2) (9+2) × 2 = 22 (см) - периметр прямоугольника .

Answer 2

Finding the Width and Perimeter of a Rectangle

To find the width and perimeter of a rectangle when the area and length are given, we can use the following formulas:

1. Width (w): - The width of a rectangle can be found using the formula: w = S / l. - In this case, the area (S) is 48 cm^2 and the length (l) is 9 cm. Therefore, the width can be calculated as: - w = 48 / 9 = 5.33 cm (rounded to two decimal places).

2. Perimeter (P): - The perimeter of a rectangle can be calculated using the formula: P = 2 * (a + b). - Given the length (a) as 9 cm and the width (b) as 5.33 cm, the perimeter can be calculated as: - P = 2 * (9 + 5.33) = 28.66 cm.

Therefore, the width of the rectangle is approximately 5.33 cm and the perimeter is approximately 28.66 cm.
