We need to find an equation in the form 
.
To find
, we use the formula:
We'll use the points
and 
:
The value of
(the y-intercept) is the value of 
when 
, which is 25.
So the equation is
(choice A).
To find
We'll use the points
The value of
So the equation is
Refer to the attached image.
Let the width of the border be 'x' inch.
Area of border = Area of rectangle ABCD - Area of rectangle PQRS
Area of rectangle ABCD =
=
= square units.
Area of rectangle PQRS =
=
= 117 square units.
So, area of border =
As it is given that the area of border is 48 square units.
So,
So, the complete equation is .
Now, we will find 'x' in the equation ,
(x-1) (x+12)=0
So, x = 1 or x = -12
Width can'not be negative.
So, x = 1 .
Therefore, the width of the border can'not be 2.5 inch.
Therefore, the width of the border is 1 inch.
