The dimensions of all parts of Triangle B is 4 times that of A
A = 1/2 b * h for the given triangle
A = 1/2 * 4b * 4h
A = 1/2 * 16 * b * h
A = 16 * (1/2 * b * h)

The area of the new triangle is 16 times the old.
16 * 15 = 240 cm^2

LekaFEV [45]

Answer:

There were 300 videos.

Step-by-step explanation:

Since there are 24 videos that got awards, and that's only 8% of the total videos, you put those together. We want the number of 100% of the videos. I would solve this by setting up a ratio and solving for $x$ . This is would look like:

$\frac{24}{8} =\frac{x}{100}$

In order to get to 100, you must multiply 8 by 12.5. Therefore, you can multiply 24 by 12.5 to complete the ratio. That would make the ratio look like:

$\frac{24}{8} =\frac{300}{100}$

Therefore there are 100% of the videos in the contest is 300.
