Question

Садовый питомник имеет прямоугольную форму. длинна питомника - 711дм, его периметр - 2148 дм. Чему равна площадь питомника? ответ в дм в квадрате

Answer 1

Ответ:

258093 дм²

Пошаговое объяснение:

P=2*(a+b)

S=a*b

2148=2*(711+b)

1074=711+b

b=363

S=258093 дм²

Answer 2

Calculation of the Area of a Rectangular Garden Nursery

To find the area of a rectangular garden nursery, we need to know the length and width of the nursery. In this case, we are given the length of the nursery as 711 dm and the perimeter as 2148 dm.

Let's assume the width of the nursery is represented by 'w' dm.

Calculating the Perimeter of a Rectangle

The perimeter of a rectangle is given by the formula: P = 2(l + w), where 'P' represents the perimeter, 'l' represents the length, and 'w' represents the width.

In this case, we are given that the perimeter is 2148 dm and the length is 711 dm. Therefore, we can write the equation as:

2148 = 2(711 + w)

Simplifying the equation:

2148 = 1422 + 2w

Subtracting 1422 from both sides:

726 = 2w

Dividing both sides by 2:

363 = w

So, the width of the nursery is 363 dm.

Calculating the Area of a Rectangle

The area of a rectangle is given by the formula: A = l * w, where 'A' represents the area, 'l' represents the length, and 'w' represents the width.

In this case, the length is 711 dm and the width is 363 dm. Therefore, we can calculate the area as:

A = 711 * 363

A = 258,393 dm²

Therefore, the area of the rectangular garden nursery is 258,393 dm².

Please note that the calculations are based on the given information and assumptions made.
