The problem figure shows the top view of an object. Identify the correct elevation from amongst the answer figures looking in the direction of the arrow.
Show Hint
The nested rectangles in the plan are stacked levels: the smaller the rectangle, the higher it stands. Redraw them as seen from the arrow side.
In the plan the outer square is the widest and lowest slab. Inside it a smaller rectangle is the next level, and the smallest rectangle is the topmost level, so the object rises in steps towards the middle. A separate narrow strip along the left side of the plan, divided from the rest by a vertical line, is a column standing on its own at the left end. Looking along the arrow (from the front), the widest slab appears at the bottom of the elevation, the next level sits above it and is narrower, and the highest level is the narrowest and tallest block, with the left strip showing as a separate tall rectangle at the left. Widths in the elevation must follow the plan widths in the ratio of the nested rectangles, and no extra vertical divisions can appear inside the slabs. Only option 1 shows a wide base slab, a narrower middle step and a still narrower tall central block together with the separate left column and no extra divisions. Answer: (1) the first figure
