Answer 3

Area = x*l
Circumference = 2x + l = 2400 --> l =?
replace to area, then take derivative of Area , let it =0 , solve for x

Answer 4

f(x)= 2x^2-2400 right? @Loser66

Answer 5

rechec.

Answer 6

2400 = 2x +l --> l = 2400 -2x, now,replace
Area = f(x) = x *l = x(2400-2x) =??

Answer 7

ohh f(x)= 2400-2x^2

Answer 8

f(x)=2400x-2x^2

Answer 9

yup, now, take derivative

Answer 10

2400x-x^2 @Loser66

Answer 11

take derivative of this

Answer 12

oh, you are good. I am solving for x also. Forgot that the question is just about "write out the equation..." hehehe.. I am sorry.

Answer 13

It is my fault. I always forget applying the break on my run. hahahaha..

Answer 14

hahaha its fine
