The surface area of a ships hull is about 11,000 square meters. What is the surface area, to the nearest tenth, of the hull of a model ship that is smaller by a scale factor of 1/100 ?
If two similar figures have lengths that are in the ratio of 1/100, their areas are in the ratio of 12/1002.
12/1002 = 1/10,000.
1/10000 of 11000 square meters is 1.1 square meter.
