Let’s begin by sketching the given diagram. We can also add in the appropriate dimensions to each side.
From the diagram we can create an equation:
l = w + w + w
l= 3w
We also know that the area is 4,800 square inches. Using the dimensions from our diagram and the formula for the area of a rectangle, we can say:
l(w + l) = 4,800
Since l = 3w, we can substitute 3w for l in the area equation l(w + l) = 4,800. Thus, we have:
3w(w + 3w) = 4,800
3w(4w) = 4,800
12w^2 = 4,800
w^2 = 400
w = ±20
Because we are dealing with a measurement, we disregard w = -20 as a solution. Thus, the width of each rectangle is 20 inches.

As shown in Figure, l = 3w
The area of each small rectangle = l*w = 4,800/4 = 12*100
=> 3w*w = 12*100
=> w = 20
Ans: B
