Question

6. A Two-story building measures 21 root

from the ground. A scale model shows the
building to be 3 inches fall. How many inches
would an 84 foot bullding be in the model?

Answer 1

12 inches

• Explanation:

So, we are going to let "x" be the height inches (in the model) of a 84 foot building.

According to the information that was given we know that the height of a two-story building is 21 feet and in the scale model its height is 3 inches.Knowing this, we can set up the following proportion:

3/21 = x/84

The final step is to solve for "x" in order to calculate its value. We get that this is: 3/21 =x/84

(84) (3/21) = x

So , an 84 foot building will be 12 inches tall in the model.

(when I do the "3/21 it doesn't mean divide it's a fraction"

Answer 2

1008 in

Explanation:

84x12=1008

84 feet times 12 inches because 12 inches is a foot.

so 84 feet times 12 inches gets your answer. 84 times 12=1008

make sense?
