Answer

$A= 8 ft^2$ A= w×(3w-2)

Work Step by Step

The formula for the Area of a rectangle is A= w×l and in this scenario, the length is 2 minus 3 times the width this l= 3w-2, therefore substituting 3w-2 for l we get A= w×(3w-2) For the question, What is the area of the rectangle when its width is 2 ft? We substitute 2 for w. w=2 A= w×(3w-2) A= (2)×(3(2)-2) $A= 8 ft^2$
