Question

Длина прямоугольника 36 см. Ширина составляет 1/4 часть его длины. Найди периметр и площадь этого прямоугольника??? Помогите решить правильно....

Answer 1

А=36, в=9. 36:4=9 Р=(36+9)*2=90см S=36*9=324cм^2

Answer 2

S=a*b- площадь прямоугольника
P=2*(a+b)- периметр
а=36 см, b=36*1/4=9 (см)-ширина
S=36*9=324 (cм2)
Р=2*(36+9)=2*48=96 (см)

Answer 3

Problem Analysis

We are given the length of a rectangle as 36 cm, and the width is 1/4 of its length. We need to find the perimeter and area of this rectangle.

Solution

To find the width of the rectangle, we can calculate 1/4 of its length: Width = (1/4) * Length

Now, we can substitute the given values to find the width: Width = (1/4) * 36 cm

To find the perimeter of the rectangle, we can use the formula: Perimeter = 2 * (Length + Width)

To find the area of the rectangle, we can use the formula: Area = Length * Width

Let's calculate the width, perimeter, and area of the rectangle.

Calculation

Given: Length = 36 cm

Calculating the Width: Width = (1/4) * 36 cm Width = 9 cm

Calculating the Perimeter: Perimeter = 2 * (Length + Width) Perimeter = 2 * (36 cm + 9 cm) Perimeter = 2 * 45 cm Perimeter = 90 cm

Calculating the Area: Area = Length * Width Area = 36 cm * 9 cm Area = 324 cm^2

Answer

The width of the rectangle is 9 cm. The perimeter of the rectangle is 90 cm. The area of the rectangle is 324 cm^2.
