Question

The Surface Area of a car frame is about 200ft squared. What is the Surface Area, to the nearest 10th of a square foot, of a model of a car that is smaller by a Scale Factor of 1/12?

Answer 1

The answer is 1.39 ft²

This is a proportion:
x : 200 ft² = (1 : 12)²
x : 200 ft² = 1 : 144
x = 200 ft² * 1 : 144
x = 1.39 ft²
