30 inch. by 12 inch 120 inch² 240 inch²

30 inch. by 18 inch 180 inch² 360 inch²

12 inch. by 15 inch 60 inch² 120inch²

18 inch. by 15 inch 90 inch² 180inch²

We find the areas and multiply by 2/3 to get the answers

30 * 12= 360 inch²

2/3 * 360 = 240 inch²

30 * 18= 540 inch²

2/3 * 540 = 360inch²

12 * 15= 180 inch²

2/3 * 180 = 120 inch²

18 * 15= 270 inch²

2/3 * 270 = 180inch²
