Area 1 = 6 x 3 = 18
Area 2 = 12 x 6 = 72
Ratio = 18 : 72
Ratio = 1 : 4
Area 1=6 x 3 =18 Area 2 = 12 x 6 = 72 Ratio =18 : 72 =:4

Answer:
Ratio of the area = 4 : 1
Step-by-step explanation:
Given : A rectangle has a length of 6 cm and a width of 3 cm.Each side is doubled in length.
To find : What is the ratio of the areas of the two rectangles.
Solution : Length = 6 cm.
Width = 3 cm .
Area 1 = length * width .
Area = 6 * 3
Area 1 = 18 cm².
If the each side is double :
Length = 12 cm .
Width = 6 cm .
Area 2 = 12 * 6 .
Area 2 = 72 cm².
Ratio of the area = \frac{Area2}{Area1}.
Ratio of the area = \frac{72}{18}.
Ratio of the area = 4 : 1
Therefore, Ratio of the area = 4 : 1
