Question

You have 332 feet of fencing to enclose a rectangular region. What is the maximum area?

A. 6889 square feet

B. 6885 square feet

C. 110,224 square feet

D. 27,556 square feet

Answer 1

i calculated it and got A as an answer

Answer 2

yep, A

Answer 3

2L + 2W = 332
and L x W = y
so from eqn 1, L = 332/2 + W
so (332/2 + W) x W = y
166W + W^2 = y
when derivative of y = 0 = maximum area
y' = 2W + 166
0 = 2W +166
-166 = 2W
W = 83

therefore as 2L +2W =332 and w = 83, L must =83 also
so L x W =A
83 x 83 = 6889

A

Is its answer B

Answer 5

since a fence can be a cicle 332 is circumference
C=piD=2pir=332
r=332/2pi
now Area=pir^2
we have r
find the AREA
