I need help ASAP. What is the perimeter of the nonagon below?

94

Step-by-step explanation:

Add up all the sides.

94 units

Step-by-step explanation:

To find the perimeter of a shape, you need to add all the sides together:

13 + 8 + 5 + 11 + 10 + 9 + 10 + 7 + 21

= 94 units

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

happy to
