How can you decompose the composite figure to determine its area?a)as a pentagon and four semicirclesb)as two rectangles and four circlesc)as a square and four semicirclesd)as two triangles and four circles Answer: C :A square and four semi circles

For this case the first thing you should do is observe that the diameter of the four semicircles is the same. Therefore, we can decompose the figure as follows:
1) We draw the diameters of the four semicircles to form a square.
2) We divide the figure into a square and four semicircles
3) The total area is the sum of the area of the square, plus the area of the 4 semicircles.
Answer: c)as a square and four semicircles
