Answer 2

Perimeter of the Square

The perimeter of a square is the sum of all its sides. In this case, the perimeter of the square is given as 2 meters 40 centimeters. To find the perimeter in centimeters, we need to convert the meters to centimeters.

1 meter = 100 centimeters

Therefore, 2 meters = 2 * 100 = 200 centimeters.

Adding the 200 centimeters to the given 40 centimeters, we get a total of 240 centimeters for the perimeter of the square.

Finding the Area of the Square

To find the area of a square, we need to know the length of one side. Since the perimeter is given, we can use the formula for the perimeter of a square to find the length of one side.

The formula for the perimeter of a square is P = 4a, where P is the perimeter and a is the length of one side.

In this case, the perimeter is 240 centimeters, so we can write the equation as 240 = 4a.

To find the length of one side, we divide both sides of the equation by 4: a = 240 / 4 = 60 centimeters.

Now that we know the length of one side, we can find the area of the square using the formula for the area of a square, which is A = a^2, where A is the area and a is the length of one side.

Substituting the value of a, we get A = 60^2 = 3600 square centimeters.

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

Conclusion

The perimeter of the square is 240 centimeters, and the area of the square is 3600 square centimeters.
