Answer:
12 feet wide
Explanation:
We are solving for a ratio between the long side of the actual kitchen, and the long side of the house on the blueprint. To find this ratio, we divide 16 by 4 to get 4:
16/4=4
Therefore, our ratio is 4. We can multiply the width of the blueprint length (3) by the the ratio of the real width:
3*4=12
Therefore, the actual kitchen will be 12 feet wide.
