Scale drawing word problems
Use scale drawings to solve problems in real-world contexts.
Practice problem 1: Two figures
Figure is a scale image of Figure .
What is the value of ?
Practice problem 2: Map
Alexander is drawing a map of the Federal Triangle in Washington, D.C. The actual Federal Triangle has a base of feet and height of feet. Alexander needs his drawing to fit on his paper, so he decides to make the base of his triangle inches.
What scale is Alexander using?
What is the height of Alexander's triangle in inches?
Practice problem 3: Scale model
Rena is building a scale model of a real castle. Her model has a rectangular base that is feet wide and feet long.
What is the area of the base of the actual castle in square feet?
Practice problem 4: Moon challenge
The earth is approximately miles in diameter. The moon is approximately miles in diameter. The distance between the two is approximately miles.
You build a two-dimensional scale model of the earth and moon. You use a circle with a diameter of inch to model the moon.
In your model, what is the diameter of the earth in inches?
In your model, what is the distance between the moon and the earth in inches?

- Beginning in the 6th century BC with the Pythagoreans, the Ancient Greeks began a systematic study of mathematics as a subject in its own right with Greek mathematics. Around 300 BC, Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.
