On a bicycle trail, the city is painting arrows like the one shown below:

calculate the area of the arrow by decomposing it into rectangles and triangles.
148.5 square centimeters
151.5 square centimeters
171 square centimeters
195 square centimeters

The answer is 151.1 :) Hope it helps!

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
