Answer:
390 m (perpendicular to river) x 780 m (parallel to river)
Step-by-step explanation:
Let y be the length of the side parallel to the river, and let x be the length of the sides perpendicular to the river.
The total area and length of fence required are given by:
Rewriting the length of fence as a function of only x:
The value of x for which the derivate of L(x) is zero is the length of x that uses the least amount of fencing:
If x = 390 m, then:
The dimensions that will use the least amount of fencing are 390 m x 780 m
So the X coordinate is 4, and the Y is -5. The rule says X + 2, Y - 8 so (4) + 2, (-5) - 8.
It's D (6, -13)

Work : 100 x 100 , take 1 x 1 and just carry the four zeros so , 1 x 1 = 1 , carry zeros 10000
