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?
Correct!
the formulf for a square is length * 4. So you are accurate!!! :D
There's a rectangle.
On 1 side is 8 which is the Length side
I have to find out how long the width side is.
The whole perimeter has to equal 25 P=25
So if both length sides are 8 then that equals 16.
Now I have to see how much both width sides are
I did 25-16 and I got 9
then I divided 2 into 9 and got 4.5
w=4.5
Is this correct?
correct again!
Yes, your calculation is correct. The perimeter of a square is equal to the sum of the lengths of all its sides. Since a square has all four sides equal in length, you can determine the perimeter by multiplying the length of one side by 4.
In this case, since one side of the square is 8.4, you can multiply it by 4 to find the total perimeter.
8.4 x 4 = 33.6
Therefore, the perimeter of the square is indeed 33.6.
