Answer:

A_{total} = 16\ cm^2

Step-by-step explanation:

<u>Step 1:  Determine the area of the top rectangle</u>

We can tell that the total shape seems like two rectangles glued together.  We can separate the top rectangle and determine the area of it and then determine the area of the bottom rectangle and combine them.  Lets first solve the left rectangle.

A=l*w

A_{top\ rectangle}=6\ cm * 2\ cm

A_{top\ rectangle}=12\ cm^2

<u>Step 2:  Determine the area of the bottom rectangle</u>

A=l*w

A_{bottom\ rectangle}=2\ cm * 2\ cm

A_{bottom\ rectangle}=4\ cm^2

<u>Step 3:  Determine the total area</u>

A_{total}=A_{top\ rectangle}+A_{bottom\ rectangle}

A_{total}=12\ cm^2+4\ cm^2

A_{total} = 16\ cm^2

Answer:  A_{total} = 16\ cm^2

Break in middle horizontally

For square (Below)

  • Area =Side²=2²=4cm²

For rectangle

  • Area =LB=6(2)=12cm²

Total area

  • 12+4
  • 16cm²

olga nikolaevna [1]

Answer:

a. 0.8125

b. 0.1875

c. 0.03125

Step-by-step explanation:

from the information given, we can come up with the following data

Total No of students =128

Total Nos of students going to college = 48+56=104

Total Nos of students not going to college and on the honor roll= 52-48=4

a. To determine the probability of students going to college we have

P(going to college) = (total number of students going to college)/total number of students

P(going to college) = 104/128

P(going to college) = 0.8125

b. To determine the probability of students not going to college, we use the rule that says total probability is 1, hence

Pr(not going to college)=1-Pr(going to college)

Pr(not going to college)=1-0.8125

Pr(not going to college)=0.1875

c. To determine the probability of students NOT going to college  and on the pay roll we have

Pr = (Total Number of students not going to college and on the honor roll)/total number of students

Pr=4/128

Pr=0.03125
