Answer:
A common beginning geometry problem is calculating the area of standard shapes such as squares and circles. An intermediate step in this learning process is combining the two shapes. For instance, if you draw a square and then draw a circle inside the square so that the circle touches all four sides of the square, you can determine the total area outside the circle within the square.
Calculate the area of the square first by multiplying its side length, s, by itself:
\text{area} = s^2area=s

For example, suppose the side of your square is 10 cm. Multiply 10 cm × 10 cm to get 100 cm2.
