Question

If the ratio of areas of 2 squares is 225:256 then the ratio of there perimeter is???

Answer 1

so, the ratio is 225:256
i.e. 225/256
area of a square = (length of one side)^2
ratio of their sides = root of 225/root of 256
i.e.  15/16

perimeter of a square = 4*side

ratio of their perimeters = 4*15/4*16

i.e. 60:64

simplify it
60:64 = 15:16

therefore, ratio of their perimeters = 15:16

Answer 2

i hope this is helpful
