Using the area formula, we know that the width of the pan is 18 inches.

An area is a unit of measurement used to describe a region’s size on a flat or curved surface.

While a plane region or area refers to the area of a shape or planar lamina, a surface region or plane area refers to the area of an open surface or the boundary of a three-dimensional object.

So, the width of the pan will be:

We know that:

The length of a rectangular pan is exactly 4/3 the width.

The pan’s total surface area is 432in².

Formula: Area = 432 = length*width = w*4w/3

Now, calculate the width as follows:

Formula: Area = 432 = length*width = w*4w/3

4w^2/3 = 432

w^2 = 432*3/4 = 324

w = 18

Therefore, using the area formula, we know that the width of the pan is 18 inches.
