Question

Длина прямоугольника 6см,ширина в 3 раза больше.Найти периметр и площадь прямоугольника?

Answer 1

Длина - 6 см 
ширина - ? , но в 3 раза больше 
Р - ? 
S - ? 
решение : 
1 ) 6 * 3 = 18 СМ ШИРИНА 
2 ) Р = (а + b) * 2 
     Р = 42 см 
3)  S= a + b  
      s = 108 см 
ответ - Р=42см    S = 108 см 

Answer 2

Ширина-6 см
Длина-?,в 3 раза больше,чем ↑
Найти:
P,S
Решение:
6×3=18(см)-длина прямоугольника
P=(a+b)+(a+b)
2)6+18+6+18=48(cм)-P прямоугольника
S=a×b
3)6×18=108(см)-S прямоугольника
Ответ:18 см;48 см;108 см.

Answer 3

Calculating the Perimeter and Area of a Rectangle

To find the perimeter and area of the given rectangle with a length of 6 cm and a width 3 times larger, we can use the following formulas:

1. Perimeter (P): The perimeter of a rectangle is given by the formula P = 2 * (length + width). 2. Area (A): The area of a rectangle is given by the formula A = length * width.

Calculating the Width of the Rectangle

First, we need to calculate the width of the rectangle, which is 3 times the length.

Width = 3 * Length Width = 3 * 6 Width = 18 cm

Calculating the Perimeter

Now, we can calculate the perimeter using the formula P = 2 * (length + width).

P = 2 * (6 + 18) P = 2 * 24 P = 48 cm

The perimeter of the rectangle is 48 cm.

Calculating the Area

Next, we can calculate the area using the formula A = length * width.

A = 6 * 18 A = 108 cm^2

The area of the rectangle is 108 square centimeters.

Therefore, the perimeter of the rectangle is 48 cm and the area is 108 square centimeters.
