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 :

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
