You don't, but the alternative ways require a lot of high powered mathematics.
The basic point is that area is a 2-dimensional concept and, in its simplest terms, that means that to calculate area you multiply together two 1-dimensional measures to get one 2-dimensional measure. In its most simple form, the two things you multiply together are the length and the breadth (or width( of a rectangle.
you are suppose to MULTIPLY on area.
You have to multiply to find area you have to add to find perimiter
To find the perimeter you add and to find the area we multiply.
To find the area of a circle, you multiply the radius by itself [squared] and then you multiply their product by pi. To find the diameter of circle, you can a)Multiply the radius by two b) Divide the area by pi, find the square root of that product and then multiply it by two.
To find the area of something you have to multiply the lengths and the width.

It depends what you are trying to get the area of. For example, to find the area of a square or rectangle you multiply the length times the width. But to find the area of a triangle, you multiply the height times 1/2 of the base. So yes, you usually multiply to find area of a figure, but there may be more steps to the process.

To find the area of 11 and 18 you multiply it.
To find the area of something you have to multiply the lengths and the width.
multiply the length by the width to find the area
To find the area of a square you multiply its length by its width.
Multiply the length and width to find the area of both a rectangle and square.
you add the area
