4-2(B) Scale Drawing

Scale Drawing or Model Used to represent an object that is too large or too small to be drawn or built to actual size Ex: maps, blueprints, model cars, model airplanes. Scale: gives the relationship between the measurement on the drawing or model and the measurement of the real object.

Ex: 1 inch = 3 feet I in represents an actual distance of 3 feet. Ex: 1:24 1 unit represents an actual unit of 24 units. Scale Factor: ratio of a length on a scale drawing or model to the corresponding length on the real object.

A set of landscape plans shows a flower bed that is 6. 5 inches wide A set of landscape plans shows a flower bed that is 6.5 inches wide. The scale on the plan is 1inch = 4 feet. a. What is the actual length of the flower bed. b. What is the scale factor?

A map has a scale of 1 inch = 8 miles. Two towns are 3 A map has a scale of 1 inch = 8 miles. Two towns are 3.25 inches apart on the map. What is the actual distance between the two towns? What is the scale factor?

Tom is designing a room that is 20 feet long and 12 feet wide Tom is designing a room that is 20 feet long and 12 feet wide. Use a scale drawing of 0.25 inch= 4 feet. Find the measure of the rooms length on the drawing. Find the measure of the rooms width on the drawing.
