Question

Rectangle A has the length 12 and a width 8 rectangle B has length 15 and width 10. Is rectangle A and scaled copy of B if so what is the scale factor?

Answer 1

• yes
• 4/5

Explanation:

The ratio of length to width in each case is ...

length : width = 12 : 8 = 3 : 2 = 15 : 10

Since the aspect ratio of the rectangles is the same, one could be a scaled copy of the other.

The scale factor of A from B is ...

A/B = 8/10 = 4/5
