Question

Периметр прямоугольника 28см ширина 6 см найти длину прямоугольника

Answer 1

6 см * 2 =12 см - две стороны ширины

28 см - 12 см =16 см - две стороны длины

16 : 2 = 8 см одна сторона длины

Answer 2

Calculating the Length of a Rectangle

To find the length of a rectangle when the perimeter is 28 cm and the width is 6 cm, we can use the formula for the perimeter of a rectangle, which is given by:

Perimeter (P) = 2 * (length + width)

We can rearrange this formula to solve for the length (l):

Length (l) = P/2 - width

Substituting the given values: - Width (w) = 6 cm - Perimeter (P) = 28 cm

We can calculate the length using the formula: Length (l) = 28/2 - 6

Calculation

Length (l) = 14 - 6 = 8 cm

Therefore, the length of the rectangle is 8 cm.

This calculation is based on the formula for the perimeter of a rectangle and the given values of the width and perimeter.
