Question

If two adjacent sides of a parallelogram are 12 cm and 8 cm, find it perimeter​

Answer 1

Answer:

40 cm

Step-by-step explanation:

one side of a parallelogram is same as the other, like a rectangle

so 2(l + b) is the formula for both

2(12 + 8) = 2 x 20 = 40 cm

Step-by-step explanation:

$given , a = 12 cm \: \:$

$and , b = 8cm$

$now, \: perimeter \\ \: of \: parallelogram = 2(a+b)$

$= 2(8+12)$

$= 2×20$

$= 40cm$

$therefore , the \: perimeter \: of \\ parallelogram \: is \: 40cm.$
