Question

3) If the adjacent sides of a parallelogram are 4cm and 6cm, then it's
perimeter is
(a) 16 cm (b) 20 cm () 24 cm (d) 15 cm​

Answer 1

Answer:

20

Step-by-step explanation:

In parallelogram, there are two pairs of parallel side which are equal.

Consider a Parallelogram ABCD,

AB || CD, also AB = CD ( same length)

AD || BC, also AD = BC (same length)

Given that AD = BC = 4cm

and AB = CD = 6cm

Perimeter = AB+BC+CD+AD = 6+4+6+4 = 20cm
