Question

Найди площадь и периметр прямоугольника если его длина 16 см а ширина состовляет три восьмых длины

Answer 1

1) Найдём ширину.
16*3:8=6
2) Найдём площадь
S=a*b
S=16*6=96 см^2
3) Найдём периметр
P=(a+b)*2
P=(16+6)*2=44 см
Ответ: S=96 см^2, P=44 см

Answer 2

1)3/8*16см=6см
2)Периметр(P)=6см+6см+16см+16см=44cм
3)Площадь(S)=16см*6см=96см^2

Answer 3

Calculating the Area and Perimeter of a Rectangle

To find the area and perimeter of a rectangle with a length of 16 cm and a width that is three-eighths of the length, we can use the following formulas:

Area of a Rectangle: The area (A) of a rectangle is given by the formula A = length * width.

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

Calculating the Area:

The width of the rectangle is three-eighths of the length, which is 16 cm. We can calculate the width as follows: Width = (3/8) * 16 = 6 cm.

Now, we can calculate the area using the formula A = length * width: A = 16 cm * 6 cm = 96 cm^2.

Therefore, the area of the rectangle is 96 square centimeters..

Calculating the Perimeter:

We can calculate the perimeter using the formula P = 2 * (length + width): P = 2 * (16 cm + 6 cm) = 2 * 22 cm = 44 cm.

Therefore, the perimeter of the rectangle is 44 centimeters..

So, the area of the rectangle is 96 square centimeters and the perimeter is 44 centimeters.
