Detailed Solution

Concept- A circle is the intersection of all points that are drawn equally far from its center. The radius of a circle is the separation between its center and periphery. Circles are shaped like circles. Thus, there are a total of seven figures in the rectangle above. Pick out the round figures from among those figures, then count them. To calculate the proportion of circles to all the other figures in the rectangle, divide this number by the total number of figures inside the rectangle.
We must determine the number of circles to all the other figures inside the specified rectangle.
Question Image

As we can see in the graphic above, omitting the rectangle, there are a total of seven figures.
Out of which 2 are squares; 2 and 6 figures, 3 are triangles; 1, 5, 7 figures; 2 are circles; 4 and 7 figures; and 2 are squares.
Figures 4 and 7 are circles because their edges are curved, giving them a rounded form.
So, there are two circles inside the rectangle, making a total of seven figures, including the circles.
The number of circles relative to all the figures inside the provided rectangle is 2/7, or 2:7.
Hence, the correct option is 2.
