Question

The ratio of sides of parallelogram is 3 : 5 and the perimeter is 150 cm. Find the sides of parallelogram.​

Answer 1

Answer:

The ratio of two sides of parallelogram is 3 : 5 and its perimeter is 48 cm.

Let length = l and breadth = b (l >b)

Then b : l = 3: 5

=> b=

5

3l

Perimeter = 2 (l+b) = 48 cm

=> 2(l+

5

3l

)=48

=>

5

8l

=24

=> l = 15 cm

then b = 9 cm

Then sides are 15 cm, 9 cm,15cm, 9 cm.

Answer 2

• PERIMETER OF PARALLELOGRAM =2(L+B)
• =2 (3X+5X)
• 150=16X
• X=150/16=9.375
• THEREFORE,L=3×9.375=28.125
• B=5×9.375=46.875
