Is there more area shaded pink or blue?

Strategy can be more important than formulas when solving problems. By cutting and/or rearranging pieces, we can compare areas intuitively and efficiently.

As you move through the next several problems, continue to use creative strategies and your intuition about shapes to find solutions.

Given that figures A, B, and C have the same dimensions, in which figure is the area of the regions shaded purple the greatest?

Note: The green quarter-circles of A, green half-circles of B, and green full circle of C all have the same radius.

The figure consists of 6 unit squares. What is the area of the portion shaded green?

The area of the large square is 100 and all of the small, blue squares are congruent.

What is the total area shaded blue?
