Answer:

x= 8 feet   (answer : A)

Step-by-step explanation:

hello :

the perimeter is : P= 2(x+y)       y : the length      x : the width

P=40   and  y = 12    calculate : x

2(x+12) =40

divid by 2 :  x+12 =20

x=20-12

The coordinates of the pre-image of point F' is (-2, 4)

<h3>How to determine the coordinates of the pre-image of point F'?</h3>

On the given graph, the location of point F' is given as:

F' = (4, -2)

The rule of reflection is given as

Reflection across line y = x

Mathematically, this is represented as

(x, y) = (y, x)

So, we have

F = (-2, 4)

Hence, the coordinates of the pre-image of point F' is (-2, 4)
