A= 104sq. feet
Formula for the area of the rectangular room is: A=L*W( lenght times width)
because Lenght is 5 feet longer, it's going to be :L= W+5
Let's put it in a formula
(W+5)*W= 104
W^2+5W-104=0
after we solve this equation, we are going to find two answers, one is W=8
the other W=-13( this can't be solution, because it's negative, and width of the room can't be negative number)
To find a Lenght, we will add 5 feet to the widht: L=8+5=13.
So, the dimensions of the room are, 13ft and 8ft.
