Question

Периметр квадрата равен 2м 40 см найди площадь квадрата в квадратных сантимметрах

Answer 1

240см
Р=а*4
а=240:4=60см
S=60*60=3600cm²

Answer 2

А - сторона квадрата
S - площадь квадрата
P - периметр квадрата
S = a²
P = а * 4
2м 40 см = 240 см
а = 240 : 4 = 60 см
S = 60² = 3600 см² - площадь

Answer 3

Perimeter of the Square

To find the area of a square, we first need to calculate the perimeter of the square. The perimeter is the sum of all four sides of the square.

Given that the perimeter of the square is 2 meters and 40 centimeters, we need to convert this measurement to a consistent unit before proceeding with the calculation.

Converting 2 meters and 40 centimeters to a single unit: - 1 meter = 100 centimeters - 2 meters = 2 * 100 = 200 centimeters - 40 centimeters = 40 centimeters

Therefore, the perimeter of the square is 200 centimeters + 40 centimeters = 240 centimeters.

Side Length of the Square

Since a square has all sides equal in length, we can divide the perimeter by 4 to find the length of each side.

240 centimeters / 4 = 60 centimeters

Area of the Square

To find the area of the square, we need to square the length of one side. In this case, the length of one side is 60 centimeters.

Area of the square = (60 centimeters)^2 = 3600 square centimeters.

Therefore, the area of the square is 3600 square centimeters.
