help me to find it plss

Answer 1

Answer:

28 cm( two sides ) , 35( other two sides )

Step-by-step explanation:

Let the given sides are 4a and 5a. In parallelogram opposite sides are equal, so if one side is 4a then the side opposite to this will in length. Similarly with  5a.

Hence, sides are 4a , 4a , 5a and 5a.

Given, perimeter = 126 cm

⇒ sum of all sides = 126 cm

⇒ 4a + 4a + 5a + 5a = 126 cm

⇒ 18a = 126 cm

⇒ a = 126 cm / 18

⇒ a = 7  cm

  Hence, sides are 4( 7 cm ) = 28 cm

 and 5( 7 cm ) = 35 cm
