Your answer would be $28.02.
1. Find the slope using the slope formula.

2. Plug that slope and either point into an equation in slope-intercept form and solve for b.

3. Now write your answer as a slope-intercept form equation
Because the square has similar lengths, the equation would be
(7x-2)(7x-2)
We can use FOIL to solve this:
The area is 49x^2 - 28x + 4 in^2.
The correct answer it would be B
