Regular polygon area = n*side^2 / (4 * tan (180/n))
where "n" is number of sides
The formula is dependent on the side^2 term,
So, if we have an octagon that has sides 4 times as large, that means the area will be sixteen times larger.
side^2 = 4^2 = 16
So we multiply 25 cm^2 by 16 and we get
400 square centimeters.

7 because all the room contain 1//2 and Brandon has 7/1/2 i t pretty easy <span />
Answer:$344
1/5 of 400 is 80 so if you subtract that it would be $320
1/50 of $400 is 8 so if you multiply that by 3,3/50 of $400 is(8*3)24 so $320+$24=$344
The correct answer is B) 775
Why 775? Because Assume the series continues.
400+200+100+50+25=775
I hope this helps.
Have a great day. :)
