For this the aweswer is f
Answer: 
Step-by-step explanation:
We can rewrite the left hand side as a perfect square, more specifically

So, taking the square root of both sides,

<span>f(x)= 50x
</span><span>y = k x
k is variation
so k= 50
D is the right option

The perimeter of the figure or polygon is calculated by adding up the value of the sides. In this case,
Perimeter = 2 (length + width)
We are given that the length is equal to 525 ft.
1205 = (2)(525 + y)
The value of y from the equation is 77.5 ft.
Answer: 77.5 ft
