Question

Задача, это прямоугольник. Р-54 м. S-?м а-18 м нужно найти площадь и др. стороны

Answer 1

A - длина
d - ширина
1) P=(a+d)•2
d=P:2-a=54:2-18=9 (м)
2) S=a•d=18•9=162 (м2)
Ответ: d=9м
S=162м2

Answer 2

Problem:

You have a rectangle with a length of 54 meters. One of the sides, denoted as 'a', is 18 meters. You need to find the area and the other side of the rectangle.

Solution:

To find the area of a rectangle, you can use the formula: Area = length * width.

Given that the length of the rectangle is 54 meters and one side is 18 meters, we can substitute these values into the formula to find the area.

Area = 54 meters * 18 meters

Calculating this, we get:

Area = 972 square meters.

So, the area of the rectangle is 972 square meters.

To find the other side of the rectangle, we can rearrange the formula for the area:

Area = length * width

Rearranging for the width, we get:

Width = Area / length

Substituting the values we have:

Width = 972 square meters / 54 meters

Calculating this, we get:

Width = 18 meters.

So, the other side of the rectangle is also 18 meters.

In summary: - The area of the rectangle is 972 square meters. - The other side of the rectangle is also 18 meters.
