Area=length*width
let the sides perpendicular to the river be x
then the side parallel to the river is 4,700-2x
A(x)=x(4700-2x)
A(x)=4700x-2x^2
This a quadratic function with a=-2 and b=4700
thus
Maximum area occurs where x=-b/2a=-4700(-2*2)=1,175 ft
length=4700-2(1175)=2,350 ft
The answer is D. 48.
(3 x 40) + (3 x 8)
120 + 24
144
3 x Y = 144
Divide 144 by 3
144 / 3 = 48.
So the answer is 48.
