7.) If the ratio of the areas of two squares is 9:1, then the ratio of their perimeters is
(a) 2:1
foy 3:1
(c) 3:2
(d) 4:1​

Answer 1

Answer:

3:1 is the answer

Step-by-step explanation:

we know

area = side sq and

perimeter = 4s

Answer 2

3:1

let the area of first sq. be A and of second be B

A:B=9:1

or S1:S2=3:1

then perimeter =4*3:4*1=3:1
