Step-by-step explanation:
I assume the area is a rectangle, right ?
under that assumption, please remember the area of a rectangle : it is length×width.
so, we have here 2 × 8 = 16 cm²
please note, that for an area we use metric items like cm² or m², and not metric items like cm or m.
why ? because we cannot measure and describe an area just by using lines (like "how many lines of 1 cm length will fit into this area ?" does not make any sense).
instead we describe how many little squares of e.g. 1 cm side length (and therefore 1 cm² area) fit into the area.
like in our calculation above, we find based on the side lengths we can put 2 rows of 8 such little squares inside the area. altogether 16 such little squares.
and there is our result ...
