Can someone help me with this?

Shaded area is 55 units²

Step-by-step explanation:

Ignoring the white cutout, we have a rectangle of length 10 and width 7 (count the squares in each direction).  The area of this larger rectangle is

(10 units)(7 units) = 70 units².  The white area that we previously ignored has dimensions 3 by 5 units, and thus an area of 15 units²  

Subtract the latter from the former, obtaining the net area

70 units² - 15 units² = 55 units²

no

Step-by-step explanation:

omg what happend to your question? if you could edit this question i can

step-by-step explanation:

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
