The equations of two sides of a square are 5x – 12y – 65 = 0 and 5x – 12y + 26 = 0. Find the area of the square.

Answer :

Given: Two side of square are 5x – 12y – 65 = 0 and 5x – 12y + 26 = 0


To find: area of the square


Explanation:


The sides of a square are


5x 12y 65 = 0 … (1)


5x 12y + 26 = 0 … (2)


We observe that lines (1) and (2) are parallel.


So, the distance between them will give the length of the side of the square.


Let d be the distance between the given lines.



Area of the square = 72
= 49 square units
