Let the breadth be 'b'
Length = 6 + b
Perimeter = 42
Perimeter = 2*(l+b)
42 = 2*(6+b+b)
42= 12 + 4*b
4*b + 12 = 42 OR 4*b = 30...Linear equation in 1 variable
Hope it helps.

The answer is given below :
Let us consider that the breadth is x m.
Then the length is (x + 6) m
Given, the perimeter of the rectangle is
= 2 × (length + breath)
= 2 × (x + 6 + x) m
= 2(2x + 6) m
Given that,
2(2x + 6) = 42
=> 2x + 6 = 21
=> 2x = 15, which is the required linear equation in x.
Thank you for your question.
