Question

The ratio of two sides of a parallelogram is 5:3 if perimeter is 80 cm find the length of its sides​

Answer 1

Answer:

《ANSWER》

Let one side be 5x and another side is 3x so opposite sides must be 5x and 3x because it's a parallelogram and thus opposite sides are same

Perimeter = sum of all side

64=5x+3x+5x+3x

64=16x

x=4

So sides of parallelogram are 20,12,20,12.

Answer 2

Answer:

Let the parallelogram be 5x and 3x.

So, P= 2(a+b)

=> 80= 2(5x+3x)

=> 80= 2(8x)

=> 80= 16x

=> x= 80/16

=> x= 5

Hence, one parallel side= 5x = (5*5)cm = 25 cm

And, another parallel side= 3x = (3*5)cm = 15 cm
