Respuesta :

Answer: Dimensions of the flower bed before the increase are x meters  and x+9 meters.

Step-by-step explanation:

Since we have given that

A rectangular flower bed is enlarged so, its area increases by 14 m².

So, Enlarged area of flower bed = [tex]x^2+9x+14[/tex]

We need to find the dimensions of the flower bed before the increase.

so, Let the original area be 'A'

so, it can be written as :

[tex]A+14=x^2+9x+14\\\\A=x^2+9x\\\\A=x(x+9)[/tex]

Since we know the area of rectangular flower bed is Length × Breadth

So, Dimensions of the flower bed before the increase are x meters  and x+9 meters.
