Answer:

Step-by-step explanation:

To find Length or Breadth when Area of a Rectangle is given

When we need to find length of a rectangle we need to divide area by breadth.

Length of a rectangle = Area ÷ breadth.

ℓ = A ÷ b.

Similarly, when we need to find breadth of a rectangle we need to divide area by length.

Breadth of a rectangle = Area ÷ length.

Answer:

The width of the rectangle is x + 3.

Step-by-step explanation:

Given:

Area of the rectangle = 4x² + 12x

Length of the rectangle = 4x

To Find:

Width of the rectangle = ?

So,

Formula:

↬ Area = Length × Width

Now,

4x² + 12x = 4x × Width

4x² + 12x ÷ 4x = Width

x + 3 = Width

Width = x + 3

Thus, The width of the rectangle is x + 3.
