⟹ Asked :-

The ratio of two sides of a parallelogram is 3:5. If the perimeter is 64 cm, find the length of the side of parallelogram ????

⟹ Given :-

Ratio of two sides - 3:5

Perimeter of parallelogram - 64 cm

⟹ To find :-

Length of side of parallelogram ??

⟹ As we know :-

Perimeter of parallelogram - 2( side + base )

⟹ Solution :-

⟹$2(3x + 5x) = 64$

⟹$2 \times 8x = 64$

⟹$8x = \frac{64}{2}$

⟹$8x = 32$

⟹$x = \frac{32}{8}$

⟹$x = 4$

⟹$so \: 3x \: = 3 \times 4 = 12cm$

⟹$5x = 5 \times 4 = 20cm$

⟹ Answers:-

12 cm

20 cm
