Question

a model of a sports arena is being created using a scale factor of 0.04. if the actual arena is 500 meters wide, what is the width of the model?
a. 30 meters
b. 25 meters
c. 35 meters
d. 20 meters

Explanation:

Step1: Recall scale - factor formula

The formula for finding the dimension of the model is $Model\ dimension=Scale\ factor\times Actual\ dimension$.

Step2: Substitute values

We know that the scale factor is $0.04$ and the actual width is $500$ meters. So, $Model\ width = 0.04\times500$.

Step3: Calculate result

$0.04\times500 = 20$ meters.

Answer:

d. 20 meters
