$\huge\sf\pink{Answer}$

☞ Your Answer is Option A

━━━━━━━━━━━━━

$\huge\sf\blue{Given}$

✭ Long side of a parallelogram is 8 cm

✭ Shorter side is $\sf\dfrac{3}{4}$ the long side

━━━━━━━━━━━━━

$\huge\sf\gray{To \:Find}$

◈ The perimeter of the parallelogram?

━━━━━━━━━━━━━

$\huge\sf\purple{Steps}$

☯ $\underline{\sf As \ Per \ the \ Question}$

Length of longer side

➝ $\sf \dfrac{3}{4} \ of \ Longer \ side$

➝ $\sf \dfrac{3}{4} \times 8$

➝ $\sf \red{Length \ of \ shorter \ side = 6 \ cm}$

Now that we know the sides of the parallelogram we shall find the perimeter of the parallelogram with the help of,

$\underline{\boxed{\sf Perimeter_{llgm} = 2(a+b)}}$

Substituting the values,

»» $\sf Perimeter = 2(a+b)$

»» $\sf 2(8+6)$

»» $\sf 2(14)$

»» $\sf \orange{Perimeter = 28 \ cm}$

━━━━━━━━━

$\sf \bullet \: Logic \ Behind$

So here we saw that the formula to find the perimeter of the parallelogram is 2(a+b).

☆ We know that opposite sides of a llgm are equal

➳ So let one pair of equal sides are a and b

Then as per the definition of perimeter i.e perimeter is the sum of all the sides of the figure so,

➳ a+b+a+b

➳ 2a+2b

➳ Perimeter of parallelogram = 2(a+b)
