Question

Найти площадь и периметр прямоугольника со сторонами 8 см и 3 см

Answer 1

8х3=24 см²-площадь
2х8+2х3=22см-периметр

Answer 2

P=2(8+3)=22cм
S=8*3=24см

Answer 3

Calculating the Area and Perimeter of a Rectangle

To find the area and perimeter of a rectangle with sides of 8 cm and 3 cm, we can use the following formulas:

Area (S) = length (a) × width (b) Perimeter (P) = 2 × (length (a) + width (b))

Using these formulas, we can calculate the area and perimeter of the given rectangle.

Calculations

Using the given dimensions: - Length (a) = 8 cm - Width (b) = 3 cm

We can calculate the area and perimeter as follows:

Area (S) = 8 cm × 3 cm = 24 cm^2Perimeter (P) = 2 × (8 cm + 3 cm) = 22 cm Therefore, the area of the rectangle is 24 cm^2 and the perimeter is 22 cm.
