Question

lf the ratio of the areas of the two squares is 9:1 the ratio of their perimeters...

Answer 1

Area of square(1) a²

Area of square(2) b²

a²/b²= 9:1 => (a/b)²=9/1

ratios of perimeter

4a/4b= a/b

√9/1=3/1

ratio of perimeter is 3:1

Answer 2

9:1 is squars of a²:b² than ratio of there perimeters are 3:1 because area is square of perimeter
