Tourism—The city of St. Louis wants to put the following image as a welcome sign on a
billboard for tourists. The picture will be enlarged so that each 1/2 inch on the drawing will represent 7 feet in real life.


a. Will the real-life image fit on a billboard that is 30 feet tall? Explain using mathematical evidence.

SPICY Problems
1

Airplane—In a scale drawing of an airplane, 1 inch equals 3 meters. The scale drawing of the
airplane shows a length of 10 2/3 inches.

a. Draw a sketch of the scale drawing and label with its length.

b. Use the scale to find the length of the airplane in real life.

1

Gundam—Mr. H used to build figurines from a popular TV show when he was growing up. Each 1/4 inch in the figurine is supposed to represent 5 meters in real life.


a. What is the actual height of the robot?
