A farmer builds a fence for his chickens in the shape of a pentagon, as shown. Each of the 5 sides has equal
length, but the fence along the highway costs twice as
much as any one of the other 4 sides. If the total cost
of fencing was $1800, how much did the highway
fence cost?

other answer is correct. i had used the radius of the radius somehow. a website:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
