Hello there!
As I am sure you probably know, area of a rectangle is the length x width. In this shape, I just divided each section into a rectangle.
Your answer will be 302cm.
Look at the way bottom area. If you just make that a 21cm x 10cm rectangle, then you have an area of 210cm.
Next, move up to the little "neck". It is 8cm tall, but we don't know how wide. You can see that on one side of it, there is 8cm of wall, and on the other, another 8cm. As you see from the bottom-most dimension, you will see that the total width for the shape is 21cm. Using this data, we can figure that the width of the "neck" is 5cm. So, 5cm x 8cm = 40cm.
Now, we have our last rectangle. It is 4cm tall, and by using our data from the last problem, we know that the width will be 13cm across (5cm+8cm). Simply multiply 13cm x 4cm, and then you will find a area of 52cm.
Finally, just add up your measurements. 210cm + 40cm + 52cm = 302cm.
I hope I haven't made you bored out of your mind... I hope you can use this to solve any other problems that come up in the future!

Answer:
who would get a circular mirror? they are cursed, and reflect things wierdly. But the area is
Step-by-step explanation:
36x.
Despite it being a circular mirror, it matters the number and math words. Because of the METAL FRAME, you have to add something to fix that open area around the mirror. So the answer is 40x
Answer:
A. Taivon runs 0,285 miles for every mile he rides his bike.
B. Yes
C. No
Step-by-step explanation:
So, Taivon is running 4 miles for every 14 miles he rides his bike. We can identify a ratio of 4:14. However, both numbers have a common multiple and can be reduced to 2:7; saying that taivon runs 4 miles for every 14 miles he rides his bike is the same to say he runs 2 miles for every 7 miles he rides his bike. To find the value of this ratio, we simply divide 2 miles that Taivon runs between 7 miles he rides his bike. The value of the ratio of miles he runs for miles he rides his bike is 0,285.
Once Taivon finished his training the ratio between the of total number of miles he ran to total number of miles he cycled was 80: 280. This is consistent with his training schedule, because if we divide 80 between 280, we obtain the same value of ratio previously calculated: 0,285. This means also that the total number of miles he ran and the miles he runs on one session are multiples; the same applies for the total number of miles he rode and the miles he rides on one session. If we divide 80 between 4, we obtain 20. Furthermore, if we multiply 20 times 14, we obtain 280. We can conclude then that Taivon trained 20 days in preparation to the Duathlon.
In one training session, Taivon ran 4 miles and cycled 7 miles. The ratio of the distance he ran to the distance he cycled in this session changes and for this session is 0,571. This training session does not represent an equivalent ratio of the distance he ran to the distance he cycled, since he actually fell short in the cycling by 7 miles to his usual 14 miles riding the bike.
<h3>
Answer: 6 hours, 40 minutes</h3>
======================================================
Work Shown:
(x hours strength)/(4 hours endurance) = 5/3
x/4 = 5/3
3x = 4*5
3x = 20
x = 20/3
x = (18+2)/3
x = 18/3 + 2/3
x = 6 + 2/3
x = 6 & 2/3
He needs to spend 6 full hours, plus an additional 2/3 of an hour, on strength training.
1 hr = 60 min
2/3 hr = (2/3)*60 min
2/3 hr = 40 min
6 hr + 2/3 hr = 6 hr + 40 min
Therefore, he needs to spend 6 hours, 40 minutes on strength training.
This is equivalent to 6*60+40 = 360+40 = 400 minutes.
