Question

How can you decompose the composite figure to determine its area?

a)as a pentagon and four semicircles
b)as two rectangles and four circles
c)as a square and four semicircles
d)as two triangles and four circles
Answer: C :A square and four semi circles

Answer 1

c is the answer

Explanation:

just took the test

Answer 2

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
