The parallelogram shown below has an area of 140140140 units^2 2 squared. Find the missing base. b =b=b, equals units

Length of the base of the given parallelogram is 14 units

Step-by-step explanation:

This question is incomplete; Find the complete question in the attachment.

Area of the parallelogram (A) = 140 square units

Height of the parallelogram (h) = 10 units

Since area of the parallelogram = Base × height

A = b × h

140 = b × 10

b =

b = 14 units

Therefore, length of the base of the given parallelogram is 14 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
