Question

A toy company is building dollhouse furniture. A rectangular door of a dollhouse has a height of 7 centimeters and a width of 3 centimeters. What is the perimeter of the door on a scale drawing that uses the scale 3:5?

Answer 1

7 times 3/5 = 4.2

3 times 3/5 = 1.8

P = 2(length) + 2 (width)

P = 2 (4.2) + 2 (1.8)

P = 8.4 + 3.6

P = 12 cm
