The perimeter these expression please help me

82.8m

Step-by-step explanation:

To find perimeter of a shape, you always add up the lengths of each side,

So we can conclude from the equal looking sides on the shape, that the top and bottom are both 15, and 15x2 = 30

And that both the left and right side of the shape are 26.4, and 26.4x2 = 52.8

Then we add together

52.8 + 30 = 82.8.

i got 86 for this
