Answer:

$A_{total} = 16\ cm^2$

Step-by-step explanation:

Step 1: Determine the area of the top rectangle

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.

$A=l*w$

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

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

Step 2: Determine the area of the bottom rectangle

$A=l*w$

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

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

Step 3: Determine the total area

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

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

$A_{total} = 16\ cm^2$

Answer: $A_{total} = 16\ cm^2$

I need someone to teach me how to do at least half of these problems please help

Here, You need to substitute the value of x, and y, in the equation then check if L.H.S is equal to R.H.S or not. If they are equal then, ordered pair was correct, otherwise they are not applicable.

75) Here, oly option D can fit i the equation, we can check:
3(-5) -2(-1) = -15+2 = -13 = R.H.S
So, the pairs are valid.

76) Here, only option D is your answer,
4(2) - 4 = 8 - 4 = R.H.S

Do the same thing in every equation!

Hope this helps!
