The scale model of a building is 5.4 feet tall. if the original building is 810 meters tall, what was the scale used to make the model? explain.

Approximately 1492.126 to 3 decimal places

1 metre is 3.28084 feet to 5 decimal places

So 1 foot is 13.28084 metres.

Using scale ratio: →reduced size in fee tactual size in metres→5.4810

These are of different units so we need to convert them. I am choosing to convert feet to metres

reduced size in metres actual size in metres→5.43.28084810=5.43.28084×810≡5.42657.4804≈1492.126

if x = 1, then the answer is 3.5
