Justin wants to use 188 ft of fencing to fence off the greatest possible rectangular area for a garden. what dimensions should he use? what will be the area of the garden?
a. 89 x 99 ; 8811 ft
b. 92 x 96 ; 8832 ft
c. 94 x 94 ; 8836 ft
d. 93 x 95 ; 8835 ft

We are given the parameter of a rectangular area of 188 ft and we are asked to determine the dimensions of the rectangular area. In this case, 
 P = L + w188 = L + W
A = LWA = L *( 188-L) = 188 L - L2 dA = 188 - 2 L = 0 L = 94 ftW = 94 ft 
A = 8836 ft2
Answer then is C
