Question

If the ratio of the areas of two squares is 121:529, what is the ratio of their perimeters​

Answer 1

Step-by-step explanation:

let a be the side of one square and b be tbe side of other square

given a² : b² = 121 : 529

therefore a : b = 11 : 23

now perimeter is first square = 4a and perimeter of 2nd square is 4b

therefore 4a : 4b = 4(a : b) => 4(11 : 23) => 44 : 92 => 11 : 23
