Question

The width and length of a rectangle (in feet) are consecutive odd integers. If the length is increased by 5 feet, the area of the resulting rectangle is 60 square feet. What is the area of the original rectangle?
25 ft2
30 ft2
35 ft2

Answer 1

So here is how you solve the given problem.
Let x be the original width. 
The original length is x + 2.
The new length is (x + 2) + 5 so it is x + 7.
A = L x W
60 = (x + 7) (x)
60 = x2 + 7x
x2 + 7x - 60 = 0
Therefore, x would be equivalent to 5.
Original Area = x (x + 2)
        A = 5 (5 + 2)
       A = 35 ft.
Therefore, the answer would be 35 feet, the third option. Hope this answer helps.

Answer 2

I am assuming that you meant $25ft^2$, $35ft^2$, and $30ft^2$, as I had the same question.  Therefore, the answer is $35 ft^2$.

You're Welcooooome!:)
