Question

Длина дна прямоугольного бассейна в 5 раз больше его ширины,причём ширина на 200м меньше длины.Найти площадь дна бассейна.

Answer 1

1)200:4=50(М)-ШИРИНА

2)50+200=250(М)-ДЛИНА

3)50*250=12500(м2)-площадь

Ответ:12500м2

Answer 2

S =  Длина * Ширина

Длина = 5*Ширина ( X = 5Y)

Y = X - 200 --> X = Y + 200

//////////////////

S = 5Y * (Y + 200) = 5Y^2 + 1000, где Y - ширина бассейна)

Answer 3

Calculating the Pool Bottom Area

To find the area of the pool's bottom, we can use the given information about the pool's length and width.

Let's denote: - Length of the pool as L - Width of the pool as W

Given: - L = 5W - W = L - 200

We can use these equations to find the values of L and W.

Solving for Width (W):

Using the equation W = L - 200, we can substitute the value of L from the first equation: - W = 5W - 200 - 4W = 200 - W = 50

Solving for Length (L):

Using the value of W we just found: - L = 5 * 50 - L = 250

Calculating the Area:

The area of the pool's bottom (A) is given by: - A = Length * Width - A = 250 * 50 - A = 12500 square meters

So, the area of the pool's bottom is 12500 square meters.
