Question;

Use the scale factor 1:12 to find the missing dimension. Great white shark actually lengthy 21ft. Find the model length in inches.

Step-by-step explanation:

Given;

Scale factor = 1:12

Actual length a = 21 ft

Let m represent the model length;

The ratio of model length to actually length is given as;

m/a = 1/12

m = a/12

Substituting a=21 ft;

m = 21/12 ft

Converting to inches;

1 ft = 12 inches

So,

m = 21/12 ft × 12 inches/ft

m = 21 inches

The model length is 21 inches
