Answer:
Dimensions of the rectangular plot will be 500 ft by 750 ft.
Step-by-step explanation:
Let the length of the rectangular plot = x ft.
and the width of the plot = y ft.
Cost to fence the length at the cost $3.00 per feet = 3x
Cost to fence the width of the cost $2.00 per feet = 2y
Total cost to fence all sides of rectangular plot = 2(3x + 2y)
2(3x + 2y) = 6,000
3x + 2y = 3,000 ----------(1)
3x + 2y = 3000
2y = 3000 - 3x
y =
y = 1500 -
Now area of the rectangle A = xy square feet
A = x[]
For maximum area
A' = = 0
1500 - 3x = 0
3x = 1500
x = 500 ft
From equation (1),
y = 1500 -
y = 1500 - 750
y = 750 ft
Therefore, for the maximum area of the rectangular plot will be 500 ft × 750 ft.
two fencing 3(500+500) = $3000
other two fencing 2(750+750) = $3000
Some symbols are missing. I'm assuming you meant to put in a horseshoe symbol like so 
If so, then the contrapositive of that would be
which is the final answer.
The tilde sign
means "not" so writing 
means "not q" which is the complete opposite of q.
If so, then the contrapositive of that would be
