Question

Длина прямоугольника 54 миллиметров а ширина на 24 миллиметров меньше Вычисли периметр и площадь этого прямоугольника

Answer 1

1) 54-24=30 мм - ширина
Р=(54+30)*2=168 мм
S= 54*30=1620 мм²

Answer 2

54-24=30 мм ширина прямоугольника
ПЕРИМЕТР=(54+30)*2=168 мм 
ПЛОЩАДЬ=30*54=1620мм²

Answer 3

Calculation of Perimeter and Area of the Rectangle

To calculate the perimeter and area of a rectangle, we need to know the length and width of the rectangle. In this case, the length of the rectangle is given as 54 millimeters, and the width is 24 millimeters less than the length.

Let's calculate the perimeter and area of the rectangle step by step.

Step 1: Calculate the Width of the Rectangle The width of the rectangle is given as 24 millimeters less than the length. Therefore, we can calculate the width by subtracting 24 from the length: Width = Length - 24 = 54 - 24 = 30 millimeters.

Step 2: Calculate the Perimeter of the Rectangle The perimeter of a rectangle is the sum of all its sides. In this case, the rectangle has two sides of length 54 millimeters (length) and two sides of length 30 millimeters (width).

Using the formula for the perimeter of a rectangle, which is P = 2 * (Length + Width), we can calculate the perimeter: P = 2 * (54 + 30) = 2 * 84 = 168 millimeters.

Therefore, the perimeter of the rectangle is 168 millimeters.

Step 3: Calculate the Area of the Rectangle The area of a rectangle is calculated by multiplying its length and width. In this case, the length is 54 millimeters and the width is 30 millimeters.

Using the formula for the area of a rectangle, which is A = Length * Width, we can calculate the area: A = 54 * 30 = 1620 square millimeters.

Therefore, the area of the rectangle is 1620 square millimeters.

To summarize: - Perimeter of the rectangle: 168 millimeters. - Area of the rectangle: 1620 square millimeters.
