Question 6
If one side of a Square is represented by
182 - 20 and the adjacent side is represented
by 42-13x, find the length of the
side
of the square.​

Answer 1

Answer:

One side of square = 18x-20

adjacent side = 42-13x

18x-20=42-13x

18x+13x=42+20

31x=62

[x=2] area of square = (18×2−20)2=(16)2=256 sq unit
