Question

1. a banner is 2 feet by 6 feet and is scaled up to 8 feet by 24 feet. what is the scale factor?

a. 5
b. 3
c. 2
d. 4

Explanation:

Step1: Calculate scale - factor for length

Scale factor for length = $\frac{\text{new length}}{\text{original length}}=\frac{8}{2} = 4$

Step2: Calculate scale - factor for width

Scale factor for width = $\frac{\text{new width}}{\text{original width}}=\frac{24}{6}=4$
Since the scale factor is the same for both length and width, the overall scale factor is 4.

Answer:

d. 4
