Me! i can’t find the perimeter of this shape

not sure but this should be it

To work out the length of an arc, we use the following equation:

 (r stands for radius)

So just substitute in the values to get the arc length of the first sector:

(angle = 40, radius = 12)

For the other sector, the angle will also be 40, since opposite angles are the same. So to get the arc length, we substitute in:

(angle = 40, radius = 5)

Now to get the perimeter, we add up all of the arc lengths and side lengths:

Perimeter =  cm or 45.87cm rounded to 2 decimal places.
