12.57" cm"

Explanation:

"given two similar figures then "

• "linear ratio "=a:b

• " area ratio "=a^2:b^2

• " volume ratio "=a^3:b^3

"here area ratio "=49:16

rArr"linear ratio "=sqrt49:sqrt16=7:4

rArr"larger part of ratio"/"smaller part of ratio"="larger perimeter"/"smaller perimeter"

"we want the smaller perimeter (p)"

rArr7/4=22/plarrcolor(blue)"cross multiply"

rArr7p=4xx22

rArrp=(4xx22)/7~~12.57" cm to 2 dec. places"
