Question

20. If the ratio of areas of two squares is 225: 256, then the ratio of their perimeters is​

Answer 1

Answer:

225/256=x2/X2

15/16=x/X

now for perimeter

4x/4X

X/X

15/16

Answer 2

Answer:

let l be side of square 1

and L be side of square2

area of square 1 225

_____________ = ___

area of square 2 256

l × l 225

____ = ___

L × L 256

l = 15

L = 16

perimeter of square 1 = 4 × l

= 4 × 15

= 60

perimeter of square 2 = 4 × L

= 4 × 16

= 64

ratio = perimeter of square 1

-------------------------------

perimeter of square 2

= 60

-----

64

= 15

-----

16
