Question

плащадь стекла прямоугольной формы-24квадратный дм..длина стекла 6дм. найди периметр стекла

Answer 1

S=a*b (a и b - стороны прямоугольника)
а=6дм
b=S/a
b=24/6=4дм
P=2*(a*b)
P=2*(6*4)=48дм
Ответ: 48 дм

Answer 2

Calculating the Perimeter of a Rectangular Glass

To find the perimeter of a rectangular glass with an area of 24 square dm and a length of 6 dm, we can use the formula for the perimeter of a rectangle, which is given by:

Perimeter = 2 * (length + width)

Given that the area of the rectangle is 24 square dm and the length is 6 dm, we can calculate the width using the formula:

Area = length * width

Calculating the Width of the Glass

To find the width, we can rearrange the formula for the area of a rectangle:

width = Area / length

Substituting the given values:

width = 24 / 6 = 4 dm

Calculating the Perimeter

Now that we have the length and width, we can calculate the perimeter using the formula:

Perimeter = 2 * (6 + 4) = 2 * 10 = 20 dm

So, the perimeter of the rectangular glass is 20 dm.
