Kendall is designing a backyard garden. She makes a scale drawing of the garden where 3 inches is equivalent to 2 feet in the garden. The fence is rectangular in shape and is 21 inches long by 9 inches wide in the scale drawing. Use this information to determine the actual length and width of the fence in Kendall's garden.

length = 14 feet  width = 6 feet

Step-by-step explanation:

you can use rational fractions so...

3/2=21/x         x=14

3/2=9/x          x=6

the x will convert inches to feet
