Question

Площадь прямоугольника равна 18кв.см.ширина прямоугольника равна 3см. найди периметр прямоугольника

Answer 1

18 : 3 – 6 (см)- его длина (6*2)+(3*2)-18(см) - его пертиметр .

Answer 2

18/3=6- длинна прямоугольника
периметр равен ( а+в)*2 следовательно он равен
2*(6+3)=18

Answer 3

The Question

The question is: A rectangle has an area of 18 cm^2. The width of the rectangle is 3 cm. Find the perimeter of the rectangle.

My Analysis

The area of the rectangle is given as 18 cm^2. The formula for the area of a rectangle is: `Area = Length x Width` We are given: - Width = 3 cm - Area = 18 cm^2 To find the length, we can use the area formula: `18 cm^2 = Length x 3 cm` `Length = 18 cm^2 / 3 cm = 6 cm`

Finding the Perimeter

The perimeter of a rectangle is the sum of all its sides. Since we know: - Length = 6 cm - Width = 3 cm We can use the formula: `Perimeter = 2 x (Length + Width)` `Perimeter = 2 x (6 cm + 3 cm)` `Perimeter = 2 x 9 cm` `Perimeter = 18 cm`

Therefore, the perimeter of the rectangle is 18 cm.
