What is the area of this figure?
KatRina [158]
Hi!

I have attached 2 images that should help you understand :)

First, look at the edits I made to the image you posted. I separated the shape into smaller shapes so that we can find the area of each individual one. 

Let's start with the rectangle.

To find the area of a rectangle, multiply the width times the height. 
10 · 4 = 40

Rectangle = 40cm

Next up, the red triangles.

I have included another image showing the triangles combined into rectangles. So we can find the area of the triangles just like we would rectangles!

(let me know if you don't understand how I found the width + height of the triangles)

5 · 10 = 50

Red triangles = 50cm

And finally, the green triangles.

8 · 7 = 56

Green triangles = 56cm

Add it all together and you get...

40 + 50 + 56 = 146

The answer to the question is 146cm.

Next time you are having trouble with something like this, picture the triangles as rectangles! :)

Andrea bought 1 2/5 pounds of avocados at $4.20 per pound and ​ 2 1/
guapka [62]

Answer:

$14.43¢

Step-by-step explanation:

We are given; 1\frac{2}{5} pounds, 1 pound = $4.20 and 2\frac{1}{4} pounds,1 pound = $3.80 that Andrea bought.

Now we need to find her total cost. To do that, we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert 1\frac{2}{5} to a decimal. It is 1.4. Now we can set up a graph.

<u>Avocados</u>

\frac{4.2}{1}=\frac{x}{1.4}

Switch sides

\frac{x}{1.4}=\frac{4.2}{1}

Apply rule: \frac{a}{1}=a

\frac{x}{1.4}=4.2

Multiply both sides by 1.4

\frac{1.4x}{1.4}=4.2\cdot \:1.4

Simplify

x=5.88

So, her cost for avocados is $5.88¢

Now we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert 2\frac{1}{4} to a decimal. It is 2.25. Now we can set up a graph.

<u>Asparagus</u>

\frac{3.8}{1}=\frac{x}{2.25}

Switch sides

\frac{x}{2.25}=\frac{3.8}{1}

Apply rule : \frac{a}{1}=a

\frac{x}{2.25}=3.8

Multiply both sides by 2.25

\frac{2.25x}{2.25}=3.8\cdot \:2.25

Simplify

x=8.55

So, her cost for asparagus is $8.55¢

<u>Total cost</u>

Now that we have found out how much both of the fruits Andrea bought costs, we need to sum it up (meaning add it) to find the total cost:

$5.88¢ + 8.55¢ =

5.88 + 8.55 = 14.43

Therefore, Andrea's total cost of the fruits is $14.43¢
