Step-by-step explanation:
<u>Area of the Square Shape</u>
Given a square of side length x, the area is calculated by the formula:

It's given a square of side x is cut out of a larger square of side y. Please refer to the image below.
The area of the square of side length y is:

The shaded area of the remaining figure is the difference between both areas:


The area of the remaining figure is 
Is there anymore details to this?

Step-by-step explanation:
Answer:
y = 
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 7 when x = 3
k =
=
, thus
y =
x ← equation of variation
When x = 7, then
y =
× 7 =
