If one side of a square is represented by 18x – 20 and the adjacent side is represented by 42 – 13x, find the length of the side of the square.

Answer :

Given, one side of a square is 18x – 20 and adjacent side is 42 – 13x.


We know that, all the sides of a square are always equal.


18x – 20 = 42 – 13x


18x + 13x = 42 + 20


31x = 62



x = 2 units


Hence, the side of the square is (18 × 2) – 20 = 36 – 20 = 16 units.
