The area of a pentagon is found through the following formula:
![A = \frac{1}{4} \sqrt{5(5+2 \sqrt{5}) } * s^{2}](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7B1%7D%7B4%7D%20%20%5Csqrt%7B5%285%2B2%20%5Csqrt%7B5%7D%29%20%7D%20%2A%20s%5E%7B2%7D%20)
s is equal to the side length.
Plug 12 and 28 into the formula.
A(12) = 247.75
A(28) = 1348.85
Divide the first result by the second result.
![\frac{247.75}{1348.85}](https://tex.z-dn.net/?f=%20%5Cfrac%7B247.75%7D%7B1348.85%7D%20)
≈

9/49.
The answer is B. Please give brainliest
First, we see how many photos can be printed in a minute. We do know that it can print 28 photos in 8 minutes.
To find how many photos it can print in 1 minute, we divide 28 by 8.
28÷8=3.5
The printer can print 3.5 photos per minute.
To see how many minutes it will take to print 35 photos, we divide 35 by 3.5.
35÷3.5=10.
It will take 10 minutes to print 35 photos.
Have a nice day! :)
