Find the perimeter of each rectangle or square.

s=sides

s=34

I think the shape is the square cause the square has all even sides so 34x4=136

Is this correct?

Right.

Find the perimeter of each rectangle or square.

L=length
W=width

L=45
W=20
45+45+20+20=130

Correct??

Yes, your answer is correct. The shape described has all sides of equal length, which indicates that it is a square. To find the perimeter of a square, you multiply the length of one side by 4, since all sides are equal. In this case, since the length of each side is 34 units, the perimeter is 34 x 4 = 136 units. Well done!
