Question

Kyra was building a bed for her dollhouse. She used her bed, which is 4 feet × 5 feet, as a guide. She scaled down the dimensions of her bed by a factor 1 over 5. What are the dimensions of the model bed she built?

0.08 foot × 0.10 foot
0.40 foot × 0.50 foot
0.80 foot × 1.00 foot
0.04 foot × 0.05 foot

Answer 1

Answer: third option

Explanation:

You have the following information given in the problem:

- The dimensions of Kyra's bed is:

`4feet*5feet`

- The scale factor she used was:
`(1)/(5)`

Therefore, keeping the above on mind, you can find the the dimensions of the model bed she built by multipliying the dimensions of her bed by the scale factor:

`(1)/(5)*4ft=0.80ft\\\\(1)/(5)*5ft=1.00ft`

Then, the answer is:

`0.80ft*1.00ft`
