Here is the answer of the given question above. The attached file is already given which is a trapezoid. In order to get the answer, follow this solution:
AB=8
DC=12
AD = √(2^2 + 2^2 )
BC = √(2^2 + 2^2 )
ABCD = 8 + 12 + √(2^2 + 2^2 ) + √(2^2 + 2^2 ) = 25.66
Again, a perimeter is the distance around a two-dimensional shape. Therefore, the perimeter of this trapezoid is 22.56. Hope this answer helps.
