Step-by-step explanation:

Given,

area of a new rectangle is 4 square metres less than the area of the original rectangle .

So,

a balanced equation can be formed like this :

{x}^{2} + 3x + 4 = {x}^{2} + 5x

{x}^{2} - {x}^{2} + 3x + 4 = 5x

Cancelling +x² and -x²,

we have,

3x + 4 = 5x

4 = 5x - 3x

4 = 2x

x = \frac{4}{2}

x = 2

So,

Length = x + 5 m = 2 + 5m = 7m

Breadth = x = 2m

Thus,

the length and breadth of the rectangle will be 7m and 2m respectively
