Answer:
10.8 units
Explanation:
As the equation represents the area of a rectangle
i.e.
length * width = Area
Now area is 285.12 units square
while length is 26.4
and width is represented by w
now putting in the formula it will become
26.4 * w = 285.12
dividing both sides by 26.4

this will become
w = 10.8 units
Which is the required width of the Rectangle
so answer is 10.8 units
