Answer: The length of the rectangle is 76 feet and the width of the rectangle was 25 feet that is extended by x feet. Step-by-step explanation: The total area, in square feet, of a rectangular stage that has been widened by x feet, is represented by 1,900 + 76x. Now, factorizing the expression for the area we get, A = 1900 + 76x ⇒ A = 76(25 + x) Therefore, from the above expression, we can assume that the length of the rectangle is 76 feet and the width of the rectangle was 25 feet that is extended by x feet.
