Question

16. PQRS is a parallelogram, in which PQ = 12 cm and its perimeter is 40 cm. Fine
the length of each side of the parallelogram.
​

Answer 1

Answer:

16 cm

Step-by-step explanation:

perimeter of parallelogram :- 2(a+b)

40 cm = 2(l + 24)

40 cm = l + 24

40 cm - 24 cm = l

16 cm = l

Length = 16 cm

Answer 2

Answer:

THE SIDES ARE 12cm, 8cm, 12cm and 8cm

Step-by-step explanation:

Let PQ = RS = x and SP = QR = y   [Opposite sides are equal]

Given that PQ = 12

thus RS = 12

Perimeter of parallelogram = PQ + QR + RS + SP

40 = 12 + 12 + y + y

40 = 24 +2y

40 - 24 = 2y

16 = 2y

y = 8

THE SIDES ARE 12cm, 8cm, 12cm and 8cm
