opposite sides of a parallelogram are equal so 3:4 is for measurement of adjacent sides.
length is greater than breadth so given length
4.2=length i.e. 4x and unknown breadth =3x.
If 4x=4.2
x=4.2÷4
x=1.05cm
Breadth = 3x=1.05×3= 3.15
so length = 4.2cm and breadth =3.15
Finally perimeter of a parallelogram is 2(L+B)
2(4.2+3.15)
2×7.35= 14.70cm^2 (ANS)

Answer:
14.70cm
Step-by-step explanation:
w/l =3x/4x
4x=4.2
4÷4.2
x=1.05
L=4x=4×1.05cm=4.20cm
W=3x =3×1.05cm =3.15cm
perimeter of parallelogram =2(4.20+3.15cm)
=2×7.35cm
=14.70cm
