Question

the ratio of two sides of parallelogram os 3:5 and its perimetre is 48 then the length of sides is​

Answer 1

Answer:

length of its side are 9 and 15

Answer 2

${\Huge {\fbox{\bf {\red{Given:-}}}}}$

Ratio of two sides of parallelogram are 3 : 5.

Perimeter is 48 m

${\Huge {\fbox{\bf {\blue{To \:Find:-}}}}}$

The sides of parallelogram.

${\Huge {\fbox{\bf{\green{Solution:-}}}}}$

Let the common multiple be x.

Let the sides be 3x and 5x respectively.

$\Large\bf {\underline{\boxed{\pink{Perimeter=2×(l+b)}}}}$

$\bf :\implies 48=2 (3x + 5x )$

$\bf :\implies 48 = 2 × 8x$

$\bf :\implies \dfrac{48}{2} = 8x$

$\bf :\implies 24 = 8x$

$\bf :\implies x = \dfrac{24}{8}$

$\bf :\implies x = 3$

Hence, the value of x is 3 m

Now,

3x = 3 × 3 = 9

5x = 5 × 3 = 15

Hence , the sides of parallelogram are

9 m and 15 m.
