Composite Figures

Overlap, inscribe, and circumscribe a collection of simple geometric shapes to make a complex, composite figure. See more

A circle with radius 12 has its center at one vertex of a square. If the square has side length 12, find the area of the red region.

If each unit circle passes through the centers of the other 2 circles, what is the perimeter?

Do not include the parts that are contained within the figure.

I have a square with side length 10.
I cut out 4 rectangles from each of its corners as shown above.
What is the perimeter of this new figure?

The above figure shows five congruent rectangles. A trapezoid is drawn in such a way that its vertices coincide with vertices of some of the rectangles. What percentage of the figure is shaded?

In the diagram above, a yellow regular hexagon lies inside a larger regular hexagon with twice as large a side length.

Each of the 3 line segments connecting the inner and outer hexagons has the same length as a side of the yellow hexagon.

Is it true that the 4 colored regions have the same area?
