Question

Довжина прямокутної ділянки 40м. а ширина у 4 рази коротша, обчисли площу і периметр ділянки

Answer 1

Ответ:

S=80 м^2

Р=44 м

Пошаговое объяснение:

якщо довжина а = 40 , то ширина в = 40÷4= 10

S= ab=40×4=80

P=a+b=40+4=44

Answer 2

Calculating the Area and Perimeter of a Rectangular Plot

To calculate the area and perimeter of a rectangular plot with a length of 40m and a width 4 times shorter, we can follow these steps:

1. Calculate the Width of the Plot: - Given that the width is 4 times shorter than the length, we can calculate it as: - Width = Length / 4 - Width = 40m / 4 - Width = 10m

2. Calculate the Area of the Plot: - The area of a rectangle is given by the formula: Area = Length * Width - Area = 40m * 10m - Area = 400 square meters

3. Calculate the Perimeter of the Plot: - The perimeter of a rectangle is given by the formula: Perimeter = 2 * (Length + Width) - Perimeter = 2 * (40m + 10m) - Perimeter = 2 * 50m - Perimeter = 100 meters

Therefore, the area of the rectangular plot is 400 square meters and the perimeter is 100 meters.
