What is the length of a rectangle that has a width of 2.5 centimeters and a area of 20.5 square centimeters?

!

my teacher won't me.

8.2 cm

Step-by-step explanation:

Area = length × width

20.5 = 2.5 × length

length = 20.5/2.5

length = 8.2

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
