Answer 1

9+9=18см
36-18=18см
(9+9)*2=36см
9*9=81см2

Answer 2

Ширина-9 см
Площадь-81 см2(квадратных)

Answer 3

Given Information:

- Length: 9 cm - Perimeter: 36 cm

Calculating the Width:

To calculate the width, we need to find the missing value. Let's assume the width is represented by 'w'.

The perimeter of a rectangle is given by the formula: P = 2 * (Length + Width).

Substituting the given values, we have: 36 = 2 * (9 + w).

Simplifying the equation, we get: 36 = 18 + 2w.

Subtracting 18 from both sides, we have: 18 = 2w.

Dividing both sides by 2, we get: 9 = w.

Therefore, the width is 9 cm.

Calculating the Area:

The area of a rectangle is given by the formula: A = Length * Width.

Substituting the given values, we have: A = 9 * 9.

Simplifying the equation, we get: A = 81.

Therefore, the area is 81 square cm.
