Question

Узнайте площадь прямоугольника если его длинна 8дм а ширина на 5дм меньше покажите решение

Answer 1

Сначала надо узнать ширину 
8-5=3(дм)
Теперь нужно написать формулу
S= a * b
А потом вместо a и b написать цифры и решить пример
S = 8 *3 = 24 (см²)
Ответ : S = 24 см².

Answer 2

P=8дм-5дм=3дм2
P=8+3+8+3=22 дм2

Answer 3

Calculation of the Rectangle's Area

To find the area of a rectangle, we need to multiply its length by its width. In this case, the length of the rectangle is 8 dm, and the width is 5 dm less than the length.

Let's calculate the width of the rectangle first. Since the width is 5 dm less than the length, we subtract 5 from the length:

Width = Length - 5 = 8 dm - 5 dm = 3 dm

Now that we have the length and width, we can calculate the area of the rectangle:

Area = Length * Width = 8 dm * 3 dm = 24 dm²

Therefore, the area of the rectangle is 24 square decimeters (dm²).

Solution:

To summarize the solution: - Length of the rectangle = 8 dm - Width of the rectangle = Length - 5 = 8 dm - 5 dm = 3 dm - Area of the rectangle = Length * Width = 8 dm * 3 dm = 24 dm²

So, the area of the rectangle is 24 square decimeters (dm²).
