You could do both, but I believe you are talking about multiplying the length of one side by the length of another side to equal area.
It isn't clear what exactly you want to calculate. To calculate total area, you can add different individual areas (different pieces of a figure).
you are suppose to MULTIPLY on area.
You have to multiply to find area you have to add to find perimiter
Add.
for area you times width x length
To find the perimeter you add and to find the area we multiply.

Multiply
Add.
you add the area
Multiply for the area, add for the perimeter.
for area you times width x length
no add the sides of the area
No because you multiply the dimensions
To find the perimeter you add and to find the area we multiply.
The perimeter is the length around something, add all sides together to get the length of the perimeter.
To calculate the area you multiply the width times lenghth.the numbers that are on the side of the shape multiply them and you'll get the area. Now to get the perimeter you add the numbers on the sides together. Add lenght times width.that's how you get your perimter and area.
