The width of a rectangular dance floor is w feet. the
length of the floor is 6 feet longer than its width.
which of the following expresses the perimeter, in
feet, of the dance floor in terms of w?
a) 2w +6
b) 4w +12
c) w^2 +6
d) w^2+6w

 4w + 12

Step-by-step explanation:

The perimeter of a rectangle is given by 2 ( L + W)

Since the length is 6 feet longer than the width , this means that if the width is w then the length is w + 6

substituting this into the formula for calculating perimeter , we have

2 ( w + w + 6)

= 2 ( 2w + 6)

= 4w + 12

hope this !

let me know

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
