The length of a rectangular room is 7 less than three times the width of the room. Which expression represents the room? A. 3w-4 B. 3w-7 C. (3w x 3w) - 4w D. (3w x 3w) - 7w

Option (B)

Step-by-step explanation:

Let the width of a rectangle = w

As per given information, length of a room is 7 less than three times the width of a room

3 times of a width of a room = 3 w

Hence Length of a room = 3 w - 7

We get the length of a room = 3 w - 7

And area = L * B = w (3 w - 7)

Hence, Option (B) is correct answer
