The area of a rectangle is 28 square meters. The length is 7 meters. What is the perimeter of the square?
To find the perimeter of the square, we have to find the length of one side of the square. Since the area of the rectangle is 28 square meters and the length is 7 meters, the width of the rectangle can be calculated as follows:
Area = length × width
28 square meters = 7 meters × width
Dividing both sides of the equation by 7 meters, we find:
Width = 4 meters
Since the square has an area of 28 square meters, this means the side length of the square is the square root of 28 meters, or approximately 5.29 meters.
The perimeter of the square is calculated by multiplying the side length by 4, since all sides of a square are equal. Thus, the perimeter of the square is:
Perimeter = 5.29 meters × 4 = 21.16 meters
Therefore, the perimeter of the square is approximately 21.16 meters.
To find the perimeter of a rectangle, you need to know the lengths of its sides. However, in this case, you have mentioned the length and the area, but not the width of the rectangle. So, it is not possible to calculate the perimeter with the given information.
The formula to calculate the perimeter of a rectangle is:
Perimeter = 2 * (Length + Width)
In this case, we need to know both the length and width of the rectangle to calculate the perimeter. Please provide the width of the rectangle so that I can assist you in finding the perimeter.
