A rectangular room has an area of 12 m².the length of the room is 4m. what is the width of the room?​

3

Step-by-step explanation:

area of rectangle = length × width

so the the given area is 12

area of rectangle is 12 = 4 × width

so when we multiply 4 × 3 we get 12

and the final answer is ...

area of rectangle = length × width

4× 3 = 12

not solvable

step-by-step explanation:

we need more information, or at least an

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
