Question

If the ratio of the areas of two squares is 9:1, then the ratio of their perimeter is ?

Answer 1

3:1 is the ratio of two given sqyares

Answer 2

Heya!!!

This is your answer.

Given :-
Ratio of areas = 9:1.

We know that area = side² and perimeter is 4s.

So....
$\frac{area \: of \: first \: square}{area \: of \: second \: square} = \frac{9}{1} \\ \frac{side \: of \: first \: square}{side \: of \: second \: square} = \frac{3}{1} \\ \frac{permeter\: of \: first \: square}{perimeter \: of \: second \: square} = \frac{4 \times 3}{4 \times 1} = \frac{12}{4} = \frac{3}{1}$
Hence the ratio of perimeters is 3:1.

Hope it helps
