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?

1/5 is a 20% reduction.  So that leaves 80%

80% of 4 is 3.2 ft  (.8 x 4)   and  80% of 5 is 4 ft  (.8 x 5)

If you prefer inches, 80% of 48" = 38.4"  and 80% of 60= 48"

The dimensions of the model bed using a scale factor of 1/5 is: length is 1 foot and width is .8 feet.

What is scale factor?

"The scale factor is a measure for similar figures, who look the same but have different scales or measures. The scale factor states the scale by which a figure is bigger or smaller than the original figure."

Given dimensions of the bed is 4 feet × 5 feet.

The scale factor is (1/5).

Therefore, the length of the model bed is

= (5 × 1/5) feet

= 1 feet

The width of the model bed is

= (4 × 1/5) feet

= 0.8 feet
