Which platform has a larger perimeter – square with 4m sides or rectangular with 6m and 3m sides, and by how much?

Let’s determine what perimeter a square site with 4 m sides has (they are all equal for a square):

1) 4 * 4 = 16 (m) – the perimeter of the square area.

Now let’s calculate the perimeter of a rectangular area with sides of 6 m and 3 m:

2) 2 (6 + 3) = 2 * 9 = 18 (m) – the perimeter of the rectangular area.

Obviously, a rectangular area has a larger perimeter than a square one. To find out how much one perimeter is larger than the other, you need to subtract the smaller one from the larger value:

3) 18 – 16 = 2 (m).

Answer: rectangular by 2 m.
