Given ratio of adjacent sides
= 5:3
longer side = 7.5 cm
then for other side
as the longer side = 7.5 cm = 5x
then X = 1.5 cm
then other side = 4.5 cm
then perimeter =2( 5x + 3x )
= 2(8x)
= 2 (12)
= 24 cm
= 5:3
longer side = 7.5 cm
then for other side
as the longer side = 7.5 cm = 5x
then X = 1.5 cm
then other side = 4.5 cm
then perimeter =2( 5x + 3x )
= 2(8x)
= 2 (12)
= 24 cm
