Question

if one side of a square is represented by 8x-20 and
the adjacent side is represented by 42 - 13x, find the length of the side of the square.​

Step-by-step explanation:

all the sides of a square are equal. so,

8x-20=42-13x

21x=62

x=62/21

putting this in any of the equation

8×62/21-20

we get side of square 3.619
