There is a picture of a hexagon
On 1 of the sides it says 3.2
What is the perimeter?
I got 19.2 cause on hexagons there is 6 sides and all of them are even so 3.2x6=19.2
Is this correct?
I agree with you.
There's a square. On 1 of the sides it's 8.4
What is the perimeter?
I got 33.6 cause on each side of a square is the same size so 8.4x4=33.6
Is this correct?
Yes, your calculation is correct. The perimeter of any polygon is found by adding up the lengths of all its sides. In the case of a hexagon, which has six sides, if one of the sides is labeled as 3.2, you can multiply that value by 6 since all sides of a hexagon are equal in length.
So, 3.2 x 6 = 19.2. Therefore, the perimeter of the hexagon is 19.2 units.
