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"#
