What fractional part of the shapes are polygons

Step-by-step explanation:

We know that the polygons are the closed shapes made by combining the line segments together.

In the given picture , we have three kinds of shapes , i.e. Square , star and circle .

Since square and star are closed shapes made up of line segments but not circle, so the total polygons in the picture = 5

Total number of shapes =7

Then , the fractional part of the shapes are polygons :

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

good luck!
