Answer:

$A=48\ m^2$

Explanation:

Given that,

Width of the rectangle, b = 4 m

The length of the rectangle, l = 3b = 3(4) m = 12 m

Let A is the area of the rectangle. It is given by :

A=l* b

$A=12\ m* 4\ m$

$A=48\ m^2$

So, the area of the rectangle is
$48\ m^2$ . Hence, this is the required solution.
