Area = 304 cm^2
perimeter = 70
perimeter = 2(l+w)
70 = 2(l+w)
70/2 = l+w
35 = l+w
Now suppose the length would be = x
width would be= 35-x
NOW Area = l*w
304 = x * (35-x)
304 = 35x -x^2
x^2-35x+304 = 0
use quadratic formula to solve next ok

Answer:
the question is confusing but the answer is 2010
Step-by-step explanation:
because in the year 2000 it was
260
then increased by
60
over 5 years making the next class
320
then in 2010 it was
400
and 320 + what is 400?
80
so the answer is:
2010
Idk what the hell all that is but x = 1.802775637731995
4x^2 - 13 = 0
4x^2 = 13
13/4=3.25
x^2 = 3.25
x = ~1.8
