Calculate compound area involving just rectangles and squares, where the dimensions are given in the same units What is the area of the shaded section of this composite shape made from rectangles? ![A composite shape that looks like a staircase going up from left to right, consisting of 3 steps. The full width of the diagram is 23m, the width of the first lower step is 7m, the width of the third top step is 6m. The full height of the diagram is 22m, the height os the first lower step is 5m, the height of the third top step is 8m. The shaded section is a rectangle which starts in the top left of the second (middle) step and finishes in the bottom right of the diagram.]() \( 120 \mathrm{~m}^{2} \)
