Question

If every 3 cm on a scale drawing is equal to 4 feet in real life, which lines on the drawing would be greater than 12 feet in real life? Select all that apply. A) 12 cm B) 6 cm C) 15 cm D) 10 cm

Answer 1

C + D

Explanation:

Answer 2

Answer: C) 15 cm, D) 10 cm

Explanation:

Let's use the scale to convert the measurements on the drawing to real-life measurements in feet:

3 cm on the drawing = 4 feet in real life

To determine which lines on the drawing would be greater than 12 feet in real life, we need to find the lines on the drawing that correspond to more than 12 feet in real life.

For each line on the drawing, we can convert its length to feet using the scale:

A) 12 cm = (12/3) * 4 = 16 feet

B) 6 cm = (6/3) * 4 = 8 feet

C) 15 cm = (15/3) * 4 = 20 feet

D) 10 cm = (10/3) * 4 = 13.33 feet

Therefore, the lines that are greater than 12 feet in real life are C) 15 cm and D) 10 cm.
