Question

Площадь зала 135м2, его ширина 9м. Чему равен периметр зала?

Answer 1

135÷9=15
(15+9)×2=48 см

Answer 2

S=a*b  ;  135:9=15.   
15 м- длина зала.
P=(a+b)*2
P=(15+9)*2=48.
ответ: 48

Answer 3

Calculating the Perimeter of the Room

Given that the area of the room is 135m² and its width is 9m, we can calculate the perimeter of the room.

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

In this case, the width is given as 9m, and we need to find the length.

Calculating the Length of the Room

To find the length, we can use the formula: Area = length * width

Rearranging the formula to solve for length: length = Area / width

Substituting the given values: length = 135m² / 9m = 15m

Calculating the Perimeter

Now that we have the length and width, we can calculate the perimeter: Perimeter = 2 * (15m + 9m) = 2 * 24m = 48m

So, the perimeter of the room is 48 meters.
