Answer:
Ratio of the area = 4 : 1
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 =
.
Ratio of the area =
.
Ratio of the area = 4 : 1
Therefore, Ratio of the area = 4 : 1
