Question

Стороны прямоуг 9 дм и 11дм. Найди сторону квадрата пеоиметр которого равен периметру этого прямоуг

Answer 1

Р прямоуг. = 2 × ( а + b)

P прямоуг. = 2 × ( 9 + 11) = 40 дм.

Р квадрата = 4а, так как все стороны квадрата равны.

Сторона квадрата = 40 ÷ 4 = 10дм.

Answer 2

Calculating the Side of the Square

To find the side of a square with a perimeter equal to the perimeter of the given rectangle, we can use the formula for the perimeter of a rectangle and the formula for the perimeter of a square.

The perimeter of a rectangle is given by the formula: Perimeter = 2 * (length + width)

The perimeter of a square is given by the formula: Perimeter = 4 * side

Given: - Length of the rectangle = 11 dm - Width of the rectangle = 9 dm

We can find the perimeter of the rectangle using the formula: Perimeter of rectangle = 2 * (11 + 9) = 2 * 20 = 40 dm

Now, we need to find the side of the square with a perimeter of 40 dm. We can use the formula for the perimeter of a square: 40 = 4 * side

Solving for side: side = 40 / 4 = 10 dm

So, the side of the square with a perimeter equal to the perimeter of the given rectangle is 10 dm.
