Sides of parallelogram are 315cm and 525cm
Given:
- Sides of parallelogram are in ratio 3:5
- Perimeter of parallelogram =
To find:
- Sides of parallelogram
Solution:
Let the sides of parallelogram be 3x , 5x
We know that,
⇒1680 = 2( 3x + 5x )
⇒1680 = 2 ( 8x )
⇒1680 = 16x
⇒x =
⇒x = 105
___________________________
★ 3x = 3 × 105
=
___________________________
★ 5x = 5 × 105
=
∴ Sides of parallelogram are 315cm and 525cm
___________________________
Perimeter of parallelogram = 2(a+b)
1680 = 2(315 + 525)
1680 = 840 × 2
1680 = 1680
