Student Question

Grade 6 • 5mo.

I can't really tell if its perimeter or area when it comes to multiplication or addition. I don't really understand the surface either and I need some help right now.

Je ne peut pas toujours dire quand c'est le perimetre ou l'aire, quand il y a la multiplication ou l'addition. Je ne comprends pas la surface aussi et j'ai besoin de l'aide maintenant.

    Hi !

    It depends on the formula used in the calculation. The perimeter is calculated by additioning the measurement of the sides of the figure and the formula for the area is often a multiplication.



    The surface is synonymous with the area in geometry.
