Question

Довжина прямокутного дитячого басейну -7м,а ширина на 2м менша.Який периметр дитячого басейну? Яка довжина прямокутного басейну для дорослих, якщо його ширина на 5м більша,ніж дитячого,а периметр становить 70м?

Answer 1

Ответ:

1) 7 – 2 = 5 (м) – ширина дитячого басейну.

2) Р = 7 • 2 + 5 • 2 = 24 (м) – периметр дитячого басейну.

3) 5 + 5 = 10 (м) – ширина дорослого басейну.

4) 70 : 2 – 10 = 25 (м) – довжина дорослого басейну

Answer 2

Calculation of the Perimeter of the Children's Pool

To calculate the perimeter of a rectangular pool, we need to know the length and width of the pool. In this case, the length of the children's pool is given as 7 meters, and the width is 2 meters less than the length.

Let's calculate the width of the children's pool first:

Width = Length - 2 meters Width = 7 meters - 2 meters Width = 5 meters

Now that we have the length and width of the children's pool, we can calculate its perimeter:

Perimeter = 2 * (Length + Width) Perimeter = 2 * (7 meters + 5 meters) Perimeter = 2 * 12 meters Perimeter = 24 meters

Therefore, the perimeter of the children's pool is 24 meters.

Calculation of the Length of the Adult Pool

To calculate the length of the adult pool, we are given that its width is 5 meters more than the children's pool, and the perimeter of the adult pool is 70 meters.

Let's calculate the width of the adult pool first:

Width = Width of Children's Pool + 5 meters Width = 5 meters + 5 meters Width = 10 meters

Now that we have the width of the adult pool, we can calculate its length using the given perimeter:

Perimeter = 2 * (Length + Width) 70 meters = 2 * (Length + 10 meters) 70 meters = 2 * Length + 20 meters 2 * Length = 70 meters - 20 meters 2 * Length = 50 meters Length = 50 meters / 2 Length = 25 meters

Therefore, the length of the adult pool is 25 meters.
