We know that
[perimeter of rectangle]=2*(<span>length+width)
</span>
Let
x-----------> length
y-----------> width
so
P=2*(x+y)-----------> 244=2*(x+y)-----> x+y=122-------> y=122-x
Area=x*y-------> x*(122-x)----> 122x-x²
find the derivative function and equals to zero
122-2x=0-----> 122=2x----------> x=61 m
y=122-x------> y=122-61---------> y=61 m
<span>the maximum area is given by a square
</span>
the answer is
is a square of side 61 m

Answer- 42646.50 pounds
Area of flat surface = Area of rectangle + area of triangle
= 12.9*25 + 1/2* 7.2* 25
= 162.5 feet^2
Force exerted by wind =0 .004 * Area * velocity^2
= 42646.50 pounds
Answer:
The equation is 
whose solution is 
Step-by-step explanation:
Let us call 
the number of minutes the phone is used over 200 minutes, then we have
<em>(this says monthly bill of $40 plus the cost of phone usage over 200 minutes must equal $58 )</em>
This equation can be used to solve for u as follows:
Get the equation to slope-intercept form: y = mx + b
6x + 3y = 6
Subtract 6x from both sides. This will give you 3y = -6x + 6.
Then, divide by 3 on both sides. This gives you y = -6x + 2.
2 is your y intercept and -6 is your slope.
