The perimeter of a room is 43 ft. The width is 9 1 2ft. What is the length?

Answer: The length is 12 ft.

Step-by-step explanation:

So a room is likely to be in a shape of a rectangle. And to to find the perimeter of a rectangle will use the formula P = 2w + 2l so in this case we know the perimeter and and the width but we need to find the length.

so using the formula we could do this

43 = 2 (9.5) + 2l

43 = 19 + 2l subtract 19 from both sides

-19 - 19

24 = 2l Divide both sides by 2

l = 12

The length is 12.

Check: 43 = 2 (9.5) + 2 (12)

43 = 19 + 24

43 = 43 correct so the length is 12.
