Below are sample questions representative of the exercises included on this worksheet and related GEO.90 Use similarity for scale drawings and indirect measurement skill assessments:

Problem 1Difficulty: Mastery
A 6-foot pole and a tower form similar shadow triangles. The pole's shadow is 4.5 feet, and the tower's shadow is 54 feet. A scale drawing uses 1 centimeter to represent 6 feet. What are the tower height and its height in the scale drawing?
A54 feet and 9 centimeters
B72 feet and 12 centimeters
C81 feet and 13.5 centimeters
D108 feet and 18 centimeters
Solution & Explanation:Use 6/4.5 = h/54 to get h = 72 feet. With 1 cm representing 6 feet, the drawing height is 72 / 6 = 12 centimeters.
Problem 2Difficulty: Mastery
A model is 1/25 the length of the actual object. A student finds the model length for a 175-centimeter object by dividing 175 by 1/25 and gets 4375 centimeters. What is the correct model length?
A7 centimeters
B25 centimeters
C150 centimeters
D4375 centimeters
Solution & Explanation:A 1/25 model should be smaller than the actual object. Multiply by 1/25, or divide by 25: 175 / 25 = 7 centimeters.
Problem 3Difficulty: Mastery
A scale drawing of a triangular garden has sides 5 centimeters, 12 centimeters, and 13 centimeters. The actual longest side is 39 meters. What is the actual perimeter of the garden?
A30 meters
B78 meters
C90 meters
D117 meters
Solution & Explanation:The 13-cm side represents 39 m, so the scale is 3 meters per centimeter. The drawing perimeter is 5 + 12 + 13 = 30 cm, so the actual perimeter is 30 x 3 = 90 meters.
