Answer 1

9514 1404 393

Answer:

• perimeter: 3 : 4
• area: 9 : 16

Explanation:

The perimeter ratio smaller : larger is the same as the side length ratio.

18 : 24 = 3 : 4 . . . smaller : larger perimeter ratio

The area ratio is the square of this.

3^2 : 4^2 = 9 : 16 . . . smaller : larger area ratio
