At an outdoor festival, 2-m sections of fencing are used to enclose an area for food sales. there are 100 sections of fencing available.

Question

a) how many metres of fencing are available altogether?
my answer for question a:
100* 2 = 200m

b) determine the maximum rectangular area that could be enclosed. How does the fact that the fencing is in sections affect your answer?

can someone help me on question b and correct question A

Answer 1

correct on A.
dimensions will have to be in 2 meter increments. 100 of them. Max area will be 10 sections by 10 sections (a square), or 20 m x 20 m.

Answer 2

can you help me on question b, i really don't know how to do it

Answer 3

for a given perimeter, the square has maximum area
so, if there are 100 sections of fence, a square with 25 sections on each side will have maximum area.

(25*2)^2 = 50^2 = 2500 m^2
