Answer 2

The length of PQ = 42 cm

Given:

PQRS is a parallelogram  

The perimeter is 114 cm and QR = 15 cm  

To find:

The length of QR = 15 cm

Solution:

Given that PQRS is a parallelogram

Then PQ and RS are opposite sides

         PS and QR are opposite sides

In a parallelogram opposite sides are equal

  ⇒  PS = QR = 15 cm  

  ⇒  PQ = RS = x    (let x be the PQ )

Perimeter of Parallelogram = PQ + QR + RS + PS

⇒ x + 15 + x + 15 = 114 cm

⇒ 2x + 30 = 114

⇒ 2x = 84

⇒ x = 42 cm

Therefore, The length of PQ = 42 cm
