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.

Solution:

We know that

All sides of a square are equal

18x - 20 = 42 - 13x

By further calculation

18x + 13x = 42 + 20

31x = 62

Dividing both sides by 31

x = 2

Substituting the value of x

Side of square = 18x - 20 = 18 x 2 - 20 = 36 - 20 = 16

Therefore, the length of the side of the square is 16 units.
