One pair of corresponding sides of two similar polygons measures 12 and 15 The perimeter of the smaller polygon is 30 Find the perimeter of the larger?
The perimeter of the larger polygon will have the same ratio to the perimeter of the smaller as the ratio of the corresponding sides. Therefore, the larger polygon will have a perimeter of 30(15/12) = 37.5, or 38 to the justified number of significant digits stated.
A family is looking at a scale model of the house they are buying The model measures 6 inches by 12 inches The actual house measures 30 feet by 60 feet What is the scale of the model house?
The scale of the house is the ratio of the model to the actual house. This ratio will be the same for both directions, or else the model would be useless. 6 inches is .5 feet, so the ratio is .5:30. You always want to write ratios as 1:something, so we double both side of the ratio and get 1:60. Likewise, 12 inches is one foot, so the ratio is 1:60 for the other dimension as well, as it should be.
