Hayden Baxter · Answer 1

3 ft

Step-by-step explanation:

Perimeter is

P = 2 (l+w)

Substituting what we know

18 = 2 (6+w)

Divide each side by 2

18/2 = 2 (6+w) / 2

9 = 6+w

Subtract 6 from each side

9-6 = 6+w-6

3 = w

Eleanor Wiley · Answer 2

It's 3 ft wide because 6+6 is 12 and the perimeter is 18 and 18-12 is 6 so divide that by 2 is 3 for each side which all equals to 18
