2 W + 5 L = 750 ft
5 L = 750 - 2 W
L = 150 - 2 W / 5
A ( W ) = W * ( 150 - 2 W / 5 )
A function that models the total area:
A ( W ) = 150 W - 2 W² / 5
A` ( W ) = 150 - 4 W / 5
150 - 4 W / 5 = 0
4 W / 5 = 150
W = 187.5 ft
The largest possible area:
A = 150 * 187.5 - (2 * 187.5² ) / 5 = 28,125 - 14,062.5 = 14,062.5 ft²

Answer: h = 17
Step-by-step explanation: As a general rule, if an equation has any fractions in it, try to get rid of those fractions as soon as possible.
The quickest way to get rid of a fraction is to multiply both 
sides of the equation by the denominator of the fraction.
So in this problem, we can get rid of the fraction in our 
first step by multiplying both sides of the equation by 4.
On the left, the 4's cancel and on the right, 1(4) is 4.
Now we have h - 13 = 4.
Since 13 is being subtracted from <em>h</em>, to get <em>h</em> by itself, 
we need to add 13 to both sides of the equation to get h = 17.
Now, we can check our answer by plugging 17 back
into the original equation shown below in italics.
 
 
   
 
 
        
             
        
        
        
This question may be trick question xD haha.
Anyways, a right triangle is a triangle with a right angle (90 degrees). In your picture, that triangle is a right triangle, but the sides could be a bit slanted. Please take a picture from top view, so I can see it properly.
The triangle's length does not matter in this case. As long as it has a right angle, it's a right triangle.
