The length of the rectangle or classroom floor is 19 feet less than twice the width. which expression represents the area of the classroom floor?
a) 6w-38
b) 2w (squared) -19w
d) 3w-19

B

Step-by-step explanation:

The area is calculated by length×width. In this case you don't know the length or width precisely so you say 2w (squared) because it's the width×width and you subtract 19 because then you actually have width×length.
