The ratio of the areas of two squares is 16 : 1. Find the ratio between their perimeters.
Answer & explanation
Correct answer: option 3
The ratio of the areas of two squares = 16 ∶ 1
Let the side of the two squares be a and b respectively and we know that the ratio of the sides of any figure is equal to the ratio of the perimeters so,
The ratio of the areas of two squares = a2 ∶ b2 =16 ∶ 1
The ratio of the perimeters of two squares = a ∶ b = 4 ∶ 1
