You can solve a system of equations 3 ways.
1. Elimination
This method is eliminates one of the variables in the system of equations to get 1 equation with only one 1 variable.
2. Graph
You graph both of the equations and find where they intersect if at all.
3. Substitution
If you know the value of one of variables, you can substitute it back into the equation.
Answer:
(b) 68
Step-by-step explanation:
Distance between two points:
Suppose that we have two points,
and
. The distance between them is given by:

Diagonal:
Diagonals are a line between opposite points in a square.
In this question, it is between A(0,3) and B(5,0), and between (0,0) and (5,3). Both these diagonals have the same measure, and are the distance between these points. So

Then sum of the squares of its both diagonals is units
Both diagonals measure
. Sum of squares is:

The correct answer is given by option b.
