Answer of 10: This figure is parallelogram because because both pairs of its opposite sides are parallel.
Answer of 9 : It will be find by pythagores therom .
see, AB^2+AD^2=BD^2
so, 4x^2+3x^2=10^2
16x^2+9x^2=100
25x^2=100
(5x)^2= 100
5x=√100
5x=10
x=10/5=2
Now =AD is 3x =3×2= 6 cm
AB=4x=4×2=8 cm
these are sides.
perimetere of its is "sum of all sides.
AB+AD+BC=CD
8+6+6+8= 28 cm
