**Answer:**

False

**Step-by-step explanation:**

The Following is not a function because each input(X-Value) has more than one output(Y-Value), which violates the law of functions. The Law of Functions is that Inputs can only have one unique output.

**Answer:**

**x = 425 yard **

**y = 425 yard **

**Area = 180625 square yard **

**Step-by-step explanation:**

**given data **

fencing = 1,700 yards

**solution**

we consider here length and width is x and y

so parameter is = P

P = 2 ( x+ y)

1700 = 2 ( x+ y)

x + y = 850

x = 850 - y ...............1

and

area of rectangle is

Area = x y

area = ( 850 - y ) y

area = 850 y - y²

so for large area is

= 0

= 850 - 2y

so here

850 - 2y = 0

**y = 425 yard **

and from equation 1

x = 850 - y

x = 850 - 425

**x = 425 yard **

and

Area = 425 × 425

**Area = 180625 square yard **
