Calculate the perimeter of a rectilinear shape by adding lengths expressed in the same units What is the perimeter of this composite shape made from rectangles? ![A composite shape made from three rectangles that form a step structure.  The base of the shape is horizontal and is 23m long. The vertical height of the whole shape is 22m. The horizontal width of the top part of the shape is 6m. The horizontal width of the first step is 7m. The vertical height of the bottom rectangle is 5m.  The vertical height of the top rectangle is 8m.]() \( 88 \mathrm{~m} \)
