Question

Meghla has brought a smartphone with length is 4 unit and breadth is 3 unit, what is the screen size of the smartphone

Answer 1

Answer:

$12unit^2$

Explanation:

Assuming that the screen covers the entire area of the smart phone.

$3 * 4 = 12 unit^2$

Most likely this wouldn't be the case, so the screen size would be at most $12unit^2$

$0unit^2$

And would most likely fall under this range of answers.

Answer 2

You multiply 4 by 3 to get the screen size of the smartphone.
