Question

Francesca's making a scale drawing of the mirror on the wall in her school's hallway. The mural is 12' long by 135' wide. She's using a scale of 3 meters for every 4ft. What are the dimensions of her scale drawing?

Option 1: 9 m x 101.25 m
Option 2: 2.25 m x 30 m
Option 3: 4.5 m x 60 m
Option 4: 6 m x 80 m

Answer 1

The dimensions of Francesca's scale drawing are 9m x 101.25m. Option A is correct answer.

Step-by-step explanation:

To find the dimensions of Francesca's scale drawing, we need to apply the scale factor to the dimensions of the mural. The scale factor is 3 meters for every 4 feet, which can be simplified to 3/4.

The length of the scale drawing can be found by multiplying the scale factor by the length of the mural: 12 feet imes (3/4) = 9 meters.

Similarly, the width of the scale drawing can be found by multiplying the scale factor by the width of the mural: 135 feet imes (3/4) = 101.25 meters. Therefore, option A is correct answer.
