Answer 1

hi,
hence the length of sides of equilateral triangles r equal...
if length of one side is "x"
then the perimeter is 3x

so the rage for the perimeter can be written using...
50> 3x > 60
now solve this inequality and u will get the answer...
Can u solve it ?

Answer 2

50/3 >x>20

Answer 3

i got it... Thank You!!!
