Answer 3

Can a square with a perimeter of 28 cm have an area of 49 cm²?

To determine if a square with a perimeter of 28 cm can have an area of 49 cm², we need to calculate the side length of the square and then check if the area matches the given value.

Let's assume that the side length of the square is s. The perimeter of a square is given by the formula: Perimeter = 4s. In this case, we have a perimeter of 28 cm, so we can set up the equation:

4s = 28

Solving this equation, we find that the side length of the square is s = 7 cm.

Now, let's calculate the area of the square. The area of a square is given by the formula: Area = s². Substituting the value of s = 7 cm, we get:

Area = 7² = 49 cm²

Therefore, a square with a perimeter of 28 cm can indeed have an area of 49 cm².

Please note that the calculations above are based on the assumption that the shape in question is a square. If you have any additional information or specific requirements, please let me know, and I'll be happy to assist you further.
