Question

Jayden measured a community college and made a scale drawing. He used the scale 22 millimeters : 9 meters. The actual length of a building at the college is 99 meters. How long is the building in the drawing?

Answer 1

Hey there! :)

Answer:

x = 242 mm.

Explanation:

Begin by setting up a proportion between the actual college building and the drawing.

`(22mm)/(9m) = (x)/(99m)`

Cross multiply:

99 × 22 = 9 × x

2178 = 9x

Divide both sides by 9:

2178/9 = 9x/9

x = 242 mm.
