Question

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

Answer 1

Answer:

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
