Question

A room is 12 feet long and 10.5 feet wide. A scale model of the room is 3.5 feet wide. What is the area of the scale model?
10.3 square feet
14 square feet
36 square feet
122.5 square feet

Answer 1

dont u multiply it

Answer 2

i have no clue

Answer 3

You need a "conversion factor." If the real-life room is 10.5 feet wide, and the width of the scale model is 3.5 feet, use this info to come up with a scale factor.

Answer 4

i figured it out its 14 right?

Answer 5

Hint: 10.5 feet in real life corresponds to 3.5 feet in the model.

You'll need to use this info to calculate the length of the model, given that the real life length is 12 feet/

Please show me how you figured it out, and then I'll give you feedback.

Answer 6

okay um 3.5 goes into 10.5, 3 times

Answer 7

so that means i had to divide 12 by 3 to get the length of the model, i got 4, and multiplied that by 3.5, to get 14

Answer 8

Is a scale model usually larger or smaller than the original (real life object)?

Answer 9

smaller

Answer 10

right. but according to your calculations, the 12 foot length in real life has become 14 feet in the model. Could that be right?

Answer 11

no 14 is my answer for the question the length is 4 ft

Answer 12

I can think of at least 2 ways in which to solve this problem.

Let's set up ratios:

width ;length
model 3.5 feet ??
actual room 10.5 ft 12 ft

Answer 13

Cross multiply: (3.5 ft)(12 ft) = ??

Answer 14

the length is 4

Answer 15

Yes, I agree. Next time, please show how you got your result.

Answer 16

um ok XD
