Calculate missing lengths of shapes by geometrical inference, where the lengths given are in the same units What is the area of the shaded section of this composite shape made from rectangles? ![A composite shape that makes a backwards "L" shape from 2 rectangles.  The base of the shape is horizontal and is 11cm long. The vertical height of the whole shape is 12cm. The horizontal width of the top part of the shape is 5cm. The vertical height of the bottom rectangle is labelled 4cm. The left handed rectangle is shaded blue.]() \( 22 \mathrm{~cm}^{2} \)
