Let us write vertices of the given rectangle are PQRS.
Where Q is (c,d) and S is (a,b).
a) Now, we need to find the coordinates of P and R points.
x-coordinate for P is a and y-coordinate of P is d.
<h3>Therefore P is (a,d).</h3>On the same way, x-coordinate for R is c and y-coordinate of R is b.
<h3>Therefore R is (d,b).</h3>b) <em>Width of the rectangle is difference of y-coordinates of P and S points</em>.
<h3>Therefore, width = b - d.</h3>
Let the two integers be x and y respectively
Hence;
From the first equation ;
Substitute into the third equation
Open up the bracket
Take everything to the right hand side of the equation and you'll have a quadratic equation
Solve the quadratic equation and you'll have two roots
Substitute for each value of y in the first equation
Therefore:
Therefore the answer is A
